What is Quartz Glass?

Quartz glass is the most valuable and exceptional material due to its many special properties.

Quartz glass

Figure 1 – Sample image of small circular quartz glass

Its importance is known for its use in research and industrial applications. This would be inconceivable without the use or the aid of quartz glass.

The transparent silica glass is free from any impurities and is also known for the purest form of glass. Moreover, this glass type contains:

  • High thermal shock resistance
  • High Ultraviolet (UV) transmission
  • Low thermal expansion
  • High chemical and radiation resistance

Manufacturing quartz glass can be difficult, but with advanced manufacturing technology, it’s easiest for some manufacturers.

Moreover, silica or quartz is known to be the second-most common mineral on the planet. Therefore, you can expect it to be available wherever you are in the world!

Quartz Glass Formula

Quartz glass is comprised of multiple layers of Silicon-Oxygen Tetrahedra, or more commonly referred to as SIO4.

This purity is what allows Quartz glass to be easily machined and processed. While some quartz glass manufacturing companies are already on the move to improve it, we here at SXET think two (2) steps ahead.

We’re continuously working to improve the overall condition of our products! No matter what shape, form, or dimension you want your quartz glass to be, we’re sure that we’ll be able to help you with it!

What’s the Difference Between Borosilicate Glass and Quartz Glass?

As opposed to what you might believe in, borosilicate glass and quartz glass are two (2) of the things that are usually compared.

Borosilicate glass

Figure 2 – Different forms, shapes, and sizes of borosilicate glass

This is because of the effects and the results you can get when you use both of them – it’s usually the same.

So, how does borosilicate (boro) glass and quartz glass differ? Let’s start out by briefly discussing them.

Quartz glass, also known as silica glass, is a type of glass that often has just one or a single component of silica.

Silica or quartz glass

Figure 3 – Perfectly rounded silica or quartz glass that contains high thermal resistance

Silica glass is mostly known and popular for its coefficient thermal shock resistance, temperature resistance, excellent thermal shock properties, high levels of chemical resistance, and more.

Borosilicate glass or boro glass, on the other hand, is a type of glass that’s made from the use of electrical conductivity of glass sheets at high and varying temperatures. The primary benefits and advantages of borosilicate glass include: it has high strength, hardness, and chemical stability.

Difference in Application

Borosilicate glass is mostly known in applications where its strength and durability will be used. Some of the perfect examples of these industries and sectors include the chemical industry, jewelry industry, solar energy industry, electric light source industry, medical and pharmaceutical packaging, and the like.

On the flip side, quartz glass is usually used in applications and fields where its ability to be thermally shock resistant will be used. This would include the lighting industry, refractory industry, optical industry, and so on.

Difference in Temperature Resistance and Tolerance

Quartz glass is able to resist temperatures that can be upwards of 1,100°C. Its melting point would be around 1,700°C. Furthermore, you can use quartz glass in certain applications wherein you’ll be able to use it even in environments prone to corrosion and acid changes.

Borosilicate glass is usually seen to melt around 520°C. In terms of softening, you just need it to be around 820°C.

Those are some of the most distinctive differences between boro glass and quartz glass.

How is Quartz Glass Manufactured?

Many people do not know this, but, quartz glass is actually produced and manufactured in a one-step method.

While many of you might expect that it would entail a requiring process, it doesn’t. So, here’s how companies produce quartz glass tubes, quartz glass sheets, and circular quartz glass parts and components.

  1. Quartz sand is melted using temperatures that are able to handle it.
  2. The melting process usually happens inside a crucible made out of tungsten that has heating elements that are electric.
  3. Then, the material flows down from the crucible, passing through a bottom mold where it’s shaped into the material or the component desired (tubes, sheets, etc.)
  4. It’s then left to cool before being inspected by a glass engineer or expert.
  5. Before packaging, it’s sent to a machine that performs ultrasonic bath cleaning to rid it off of all unnecessary materials and substances on its surface.

That’s the easiest, the simplest, and the fastest way to create quartz glass. There are other methods, though most of them would require more effort, it’s not just the only way to produce and manufacture them.

Can You Temper Quartz Glass?

Tempering is the process of hardening or strengthening a glass product. In the case of quartz glass, would it be possible to perform heat tempering to it?

The quick and simple answer to that is no – it’s not possible to thermally temper quartz. This is due to the fact that quartz, in itself, already has high thermal and optical properties.

Proceeding to temper quartz glass may result in breaking or cracking of the surface.

What’s Quartz Glass’s Superior Light Transmission?

Transparent quartz glass is known for its superior light transmission characteristics.

Quartz glass tubes

Figure 5 – Quartz glass tubes that have superior light transmission levels

Compared with ordinary glass types, quartz glass has extremely high light transmission properties overall wavelengths from UV (ultraviolet) to infrared.

Moreover, this glass type is a great option for lens and sight applications because of its purification and transparency. Manufacturing of high-quality and best performance glass for technical applications mostly includes the use of quartz glass.

Quartz glass’s superior light transmittance cannot be simply achieved with any other glass type.

Quartz Glass Price

You’ll stumble upon multiple retail stores and quartz glass suppliers over the internet. You can find most of them on websites like Alibaba, India Mart, Made In China, Lab X, and many more!

But why choose to work with these middlemen if you can directly go to a quartz glass manufacturer like us here at SXET? We can produce for you the exact type of silica glass you need, without burning a hole in your pocket!

We can manufacture and produce whatever shape, form, and dimension you need!

Quartz Glass Properties

Quartz glass VS a regular glass

Figure 6 – Quartz glass on top of a regular glass – which clearly shows the difference in properties

Properties often refer to the properties or the characteristics of glass that are present in its physical state.

To give you a better view of the properties of fused silica, they include:

Property Units Value

Fused silica or fused quartz glass plate

Figure 16 – Image of fused silica or fused quartz glass in plate or square form

To help you have a better understanding of it, fused silica glass is made up of the four (4) kinds of commercial silica glass, the process or the manufacturing of fused quartz glass involves:

  1. Induction melting natural quartz glass in an inert environment or in a vacuum
  2. Fusing of quartz crystal powder via high-temperature flames
  3. Burning of SiCl4 in a hydrogen-oxygen flame
  4. Burning of SiCl4 in a water vapor-free plasma flame

Ideally, the production of these fused quartz or silica glass happens at around 3,000°F or about 1,650°C. The ideal type of process would be by using an electrically heated furnace.

Where Do You Usually Use Fused Quartz Glass?

Thanks to its properties and features, you’ll find tons of different applications of quartz glass. Among the most common of which would include:

  • Starting material for optical fiber
  • Discharge lamps
  • Benthoscopes
  • Vacuum tubes
  • Semiconductor fabrication furnaces

  • And many more!

Whatever application you may think you’ll be fine with, SXET will be able to turn that into reality. For years, we’ve been creating and manufacturing the best and the highest quality of quartz or silica glass, as well as fused quartz glass for our clients.

What’s the Difference Between Quartz, Crystal, and Glass?

In an easier sense, these three (3) make up some of the most sophisticated and the most lucrative materials in the world.

Between quartz glass and regular glass

Figure 17 – Image of regular glass (left) and quartz glass (right)

While many people identify them as products that are almost the same, they are not. Here at SXET, we want you to know and understand the differences and the distinctions between the three (3).

Crystal is such a loose term that can actually describe quite a lot of things and items. As a matter of fact, crystal can mean quartz and glass interchangeably.

When it’s used to describe glass, it basically means that the glass is only capable of being heated in lower temperatures. When it’s used to describe quartz, on the other hand, it means that it’s clear, transparent, and colorless, hence the term “crystal clear.”

Quartz glass, in comparison to regular soda-lime glass, is a type of material that’s harder, more durable, and longer-lasting. In fact, it’s one of the few materials that are capable of cutting through glass without any forceful effort, just like diamonds.

Glass simply is a material that’s made out of soda-lime ash, silica, and other materials. It’s not as hard and as cuttingly available as quartz.

Quartz Glass Color

Are you aware of the natural color of quartz glass?

Naturally, the color of quartz glass is clear or transparent. This is the reason why most of the time, quartz glass is dubbed and labeled as “rock crystal.”

The reason why it does not have a color naturally is because of its overall purity. But, as time progressed, several quartz glass manufacturers and suppliers played with the color of quartz glass.

  • Milky Quartz
  • Citrine
  • Amethyst Quartz
  • Rose Quartz
  • Smoky Quartz

Apart from these, several manufacturers came up with ways on how they can make quartz glass have some color. Of course, this transformed quartz glass and made it have quite a bit of impurity.

Other Differences Between Them

Here are some more differences you should learn about between quartz glass and regular glass:

  • Colors and palette availability
  • Chemical structure and composition
  • Silicone dioxide content (glass crystal has only up to eighty (80) percent silicone dioxide)
  • Temperature and wear resistance

UV Quartz Glass Plates

One of the more common uses and applications for quartz glass is that it can effectively be used for ultraviolet (UV) ray protection.

UV quartz glass plate

Figure 18 – UV Quartz glass plates in different dimensions and sizes

Some quartz glass manufacturing companies create UV quartz glass plates, which offer high and supreme levels of ultraviolet transparency as well as visible regions and areas.

Here at SXET, we have the right set of people, experts, and equipment to produce UV quartz glass plates. The best part about that is you can use it for a wide array of business sectors and industries, too!

Of course, these products would still have their regular properties, so, you can be sure that you’ll not have any trouble or problem in terms of assembly with other machines and equipment.

What Are the Advantages of Using Quartz Glass?

The vast majority of quartz glass manufacturing companies market their products by highlighting the advantages and the pros of using them.

Naturally, using quartz can offer tons of beneficial and advantageous feats to your products. You can get access to the vast library of advantages of using quartz glass. Some of which include, but are not limited to:

  • Precise and accurate dimensional tolerances
  • High chemical purity and resistance
  • Thermal shock resistance (high and excellent levels)

While these may seem convenient for you, you’ll still be able to get the best and the most affordable rates and prices if you purchase them from us here at SXET. Get it from us specifically to how you need it to be in!

Is Quartz Glass Transparent to UV?

If we’re talking about pure quartz glass, it doesn’t, unfortunately, filter ultraviolet rays (UV). So, yes, quartz glass is transparent when it comes to UV rays.

So, if you’re going to use it in its pure form, it runs the risk of being exposed to UV rays such as from halogen bulbs.

Should you be looking for a type of glass that’ll be able to block UV rays, you can make use of laminated glass. Based on most recent reports, laminated glass was able to block about 98 to 99% of all types and kinds of UV light.

What is Fused Silica Plate Used For?

Fused quartz or fused silica glass plates can be used for a ton of different applications. And no, the applications aren’t 100% identical to regular silica or quartz glass plates!

Fused silica glass plate

Figure 20 – Some of the common applications of fused silica glass

You’ll be able to make use of fused silica or fused quartz glass for:

  • Infrared or IR transmitting optics
  • UV optics and materials
  • Components and parts of metrology equipment
  • Industrial parts and components
  • Glass harps
  • Verrophones
  • Parts and components of aircraft and aerospace vehicles
  • Memory chips
  • And many more!

One common denominator between them, though, is that you can use both of them in many different applications.

Some of the most common sectors and industries you can use it on include consumer and business electronics, pharmaceutical and medical industries, lighting & fixtures industries, UV-related sectors, telecommunications industry, and many more!

How is Quartz Glass Extremely Pure?

A lot of people don’t know this, but quartz glass is a pure material with great light transmission properties.

Quartz glass has the property of being extremely pure. As a matter of fact, its purest form doesn’t even contain more than 0.01% impurities, overall! Most, if not all quartz glass manufacturing companies use this as a marketing strategy to sell more.

However, let us not forget that colored/tinted quartz glass can be less pure due to the chemicals and the compounds added to it. On the flip side, though, they’re more attractive and would contain the same number of unique characteristics.

There are many important factors that make quartz glass a perfect glass type for everything, from water purification with ultraviolet (UV), light and fiber optic cables, to sight glass.

The purity and resistance against extreme temperatures are what defines the importance of quartz glass.

The high purity level of glass is essential in several high-tech industries making quartz glass valuable as an optimal material.

What is the Dimensional Accuracy of the Manufacturing of Silica Glass?

At SXET, we have the best quartz glass manufacturing equipment that can give you, our customers a lot of tremendous valuable benefits.

One of these benefits is to achieve tighter and more accurate dimensional tolerances and output precision quartz glass. Therefore, you can be sure that the quartz glass we’ll produce and manufacture would be specific and accurate to what you need!

We are able to achieve dimensional tolerances up to +/-0.001mm so that you can have the maximum glass quality and performance!

Is Fused Silica the Same as Quartz Glass?

Many people, especially those who aren’t as experienced as the others, would think that fused silica glass or fused quartz glass would be the same as regular quartz glass.

However, the truth about that is, they’re not the same. Part, and probably one of the primary differences between the two is that quartz is made out of crystalline silica, while fused silica is made out of non-crystalline silica glass.

What this means is that fused silica has high transmissions in the UV spectrum compared to quartz. Moreover, fused quartz or fused silica glasses have higher levels of OH content compared to quartz.

To understand it better, we listed some of the key traits and characteristics of the two.

Quartz Key Traits

You’ll easily be able to identify quartz because of the following traits:

  • They have low levels of OH
  • Quartz is made from or crafted from naturally occurring crystalline silica or quartz grains
  • They’re amorphous
  • They are non-crystalline products
  • Quartz can retain impurities from raw materials, which affects its ultraviolet transparency

Fused Silica or Fused Quartz Key Traits

Here’s are some of the properties and traits of fused silica for you to be able to understand them more:

  • They have undoubtedly high OH levels or content
  • Fused silica glass is made from silica sand or silicon gas (non-crystalline)
  • They’re amorphous
  • They are transparent into deep ultraviolet rays
  • Fused silica is capable of retaining residual impurities from processing water vapor

This is how you can distinguish and differentiate fused quartz and fused silica from regular or pure quartz.

Can Quartz Scratch Glass?

Quartz is considered one of the hardest minerals in the world. And yes, quartz can dent or scratch glass even if the pressure is not that hard.

To give it a better comparison, in the Mohs scale, glass ranks at around 5.5. Quartz glass or quartz crystal, on the other hand, ranks at around 7. So, it’s about 1.5 points higher and harder than regular glass, which means you can scratch and make deep cuts on it.

Quartz Glass Sheet UK

In the United Kingdom, you have tons of different options to purchase quartz glass sheets. You have JohnMoncrieff, UV-Technik, Misumi, UGQ Optics, and others to source quartz glass.

They’re convenient and efficient, especially if you’re in the United Kingdom (UK). However, the main problem would be the rates and prices. Compared to working with a Chinese quartz glass manufacturer, the prices and the rates would be better, cheaper, and more affordable!

So, even if you or your business is in the UK, you can choose to work with a Chinese quartz glass supplier like us here at SXET! All of what you can get from UK quartz sheet glass manufacturers, you will be able to get with us, too!

The best part about that is you don’t have to pay high and lucrative fees for it! We can offer you quartz glass units that are at the most affordable and competitive rates possible!

Quartz Glass Sheet India

One might think that Indian quartz glass sheet suppliers are part of the countries that can offer the cheapest and the most competitive rates.

Furthermore, you have multiple options and companies to choose from. You have Kedar Scientific, LYG Quartz, Bio Mall India, and many more.

But, did you know that most of these silica glass sheet suppliers get their materials and their tools from China, too? Yes, China is the country that’s abundant with all resources needed to create and manufacture quartz glass, that’s why foreign businesses come to China for all the materials and the substances they need!

Chemical Resistance and Homogeneity of Quartz Glass

Quartz glass has a high chemical resistance, which basically means that it doesn’t react to chemicals as quickly as how we imagine it. Moreover, quartz or silica glass also has a high level of homogeneity, which means that it’s capable of sustaining the state that it’s in most of the time.

In the photolithography equipment, quartz glass is used as a lens material. This is because its contents are not easily transformed into another type of substance.

Moreover, it’s a fact that lens material requires a high level of homogeneity to be exceptionally good, and quartz has these relative properties.

The complex quartz glass applications require chemical resistance.

In general, quartz glass offers resistance against a vast library of chemicals, but there is also a limited number of chemicals, including hydrofluoric acids that are capable of eroding quartz glass.

We can perform hole drilling, CNC cutting and drilling, machining, and even adhesive sticking to the custom quartz glass that you need!

Apart from quartz glass, though, you can also consider us here at SXET to be your go-to manufacturer if you ever need Gorilla Glass, chemically strengthened glass, tempered glass, 3D tempered glass, anti-reflective (AR) glass, and many more!
