Areas of application for quartz glass plates

Applications at high temperatures

Fused silica sheets maintain their structural integrity and optical clarity even in extreme heat, making them ideal for industries where temperature fluctuations are common.

In metallurgy, for example, the ability of quartz glass plates to withstand high heat proves to be an advantage. This contributes to their use in furnaces and casting processes where extreme temperatures are essential for metal forming.

Chemical laboratories

Quartz glass shows no reaction with most chemicals, so the integrity of your experiments is maintained. The optical clarity of the fused silica plate allows for precise observation, making it ideal for applications where visual monitoring of chemical reactions is critical.

Their longevity also minimizes the risk of contamination, ensuring the accuracy of test results in pharmaceutical and biotechnological research.

Use in semiconductor production

The low thermal expansion of the quartz glass plates ensures dimensional stability during the manufacturing process, which is crucial for the precision required in semiconductor production.

At the same time, the high optical transparency of quartz plates enables precise alignment of the semiconductor layers. In addition, their purity in cleanroom environments is crucial to avoid contamination and ensure the quality and reliability of semiconductor components.

UV sterilization devices

Quartz glass plates are transparent to germicidal UV-C wavelengths and therefore ensure the effectiveness of sterilization processes. They are also resistant to the corrosive effects of UV radiation.

These properties are particularly advantageous in the healthcare and water treatment sectors: the use of quartz glass increases the efficiency and durability of UV sterilization systems and thus contributes to the overall safety and reliability of these processes.

Advantages of Quartz Glass Plates

Quartz glass flakes are a popular type in the seasonal industry and are widely used in many industries. Its development is not only the continuous innovation and progress of its own advantages such as environmental protection and high temperature resistance of materials, but also the continuous satisfaction of consumer needs, the continuous development of industry advantages, and the rapid development of the entire industry, which has improved its position in this industry from the side.

Quartz Glass Plate glass substrate is the core device in the manufacturing process of integrated circuit chips, and the market demand is huge. As the raw material of the Quartz Glass Plate substrate, the constituent quartz glass has many advantages such as good thermal stability, high optical uniformity, and radiation resistance.

Glass Is Mainly Divided Into Two Categories: Flat glass and deep-processed glass, among which there are three main types of flat glass: lead-up flat glass (two types with grooves and no grooves), flat-draw flat glass and float glass. Deep-processed glass is processed from flat glass and has a wide range of applications.

Not Easy To Scratch: The quartz content of quartz stone is as high as 93%, and its surface hardness can be as high as Mohs hardness 7, which is larger than sharp tools such as knives and shovels used in the kitchen, and will not be scratched by it.

No Pollution: Quartz stone is a dense and non-porous composite material made under vacuum conditions. Its quartz surface has good corrosion resistance to acid and alkali in the kitchen. The liquid placed on the surface only needs to be wiped off with a rag such as clean water or a cleanser, and if necessary, a blade can be used to scrape off the remaining objects on the surface.

Not Old: Quartz countertops have a shiny and new appearance after more than 30 messy Huaguang treatment processes. They will not be scratched by knives and shovels, will not be saturated with liquid substances, and will not cause problems such as yellowing and discoloration.

Glass Plate: The glass plate is polished and polished to make it transparent and lubricated, which is the glass plate. The surface of the glass plate has no ripples. The clear glass is made of glass plate.

When the flat glass is heated close to the softening point, the surface of the glass is rapidly cooled, so that the compressive stress is distributed on the surface of the glass, and the tensile stress is in the center layer. Due to the strong and equal compressive stress, the tensile stress generated by the external pressure is offset by the strong compressive stress of the glass, which increases the safety of glass use.

Specification And Details Of Quartz Glass Plate

Quartz Glass Plate is also found quite abundantly within the earth’s crust. It is already in use in its conventional form in making several high-end and high-performance consumer products, such as building boats, and in industrial use, including acting as pedestals, wafers or wafer carriers. It finds most application in high-temperature industrial operations.

Application and measurement standard of quartz glass plate

Quartz glass plates are usually colorless and transparent, with a visible light transmittance of 85 or more. Quartz glass can be divided into two categories: fused silica glass and synthetic quartz glass. Heat resistance, light transmittance, electrical insulation, and chemical stability are all very good.

Electric Light Source Industry
Quartz tube is used as a raw material for LED production. With the acceleration of the replacement process of LEDs for incandescent lamps, the market demand continues to increase. Because the scale of demand is small and relatively undisturbed, and at the same time, the gross profit margin is higher than that of the civilian field, so the entry barrier is relatively high.

Optical Fiber And Cable Industry
Silica glass material is the main auxiliary material in the process of producing optical fiber preform and optical fiber drawing. In addition, in the production process of solar cells, all kinds of quartz glass materials and products are also the main process consumables. With the rapid development and technological advancement of the domestic optical fiber industry, the proportion of localization of optical fiber preforms has gradually increased, which has also led to the development of quartz glass raw materials and auxiliary materials in the domestic optical communication field. In the future, special light sources such as automobile whole lamps and germicidal lamps may become new demand growth points.

As the application range of quartz glass plates becomes more and more extensive, there are more professional needs to use and purchase this product. The quartz glass plates on the market are also good and bad. So, in reality, how should we judge the quality of it?

Smell: To judge the quality of a quartz glass plate, it can be done by smelling the taste. If it is a good product, then it smells from a very natural stone taste. If it is some inferior products, the smell is very dense and gluey, which can be said to be a very good judgment method, and it is also very simple for everyone to grasp.

Look at the distribution of pores: You can look at the distribution of pores to judge whether it is good or bad. If it is a good product, the distribution of pores inside is very uniform, and there are no pores on the surface. Therefore, this method is also a very good judgment method.

Look at the seams: A good quartz glass plate has a very good gap treatment at each seam. When looking at the quality of a product, it can also be judged from this aspect.

How do you clean and maintain Quartz Glass Plate

Use A Mild Detergent: Prepare a solution of mild detergent and warm water. Avoid using harsh chemicals or abrasive cleaners that can damage the glass surface.

Gentle Cleaning: Dip a soft cloth or sponge into the detergent solution and gently wipe the glass surface in a circular motion. Avoid applying excessive pressure to prevent scratching.

Rinse With Clean Water: After cleaning, rinse the glass thoroughly with clean water to remove any detergent residue.

Dry With A Lint-free Cloth: Use a lint-free cloth or microfiber towel to dry the glass surface. This will prevent water spots or streaks from forming.

Avoid Contact With Sharp Objects: Be cautious when handling the glass sheets to prevent scratches. Avoid contact with sharp objects or abrasive materials.

Store Properly: When not in use, store the glass sheets in a clean and dry environment to prevent dust or dirt accumulation.

Handle With Care: When moving or transporting the glass sheets, handle them with care to avoid accidental dropping or impact that could cause breakage.

Regular Inspection: Periodically inspect the glass sheets for any signs of damage or defects. If any issues are found, consult a professional for repair or replacement.

FAQ

Q: What is quartz glass plate?

A: Quartz glass plate is a pure silica-based material that offers exceptional thermal stability, optical clarity, and chemical resistance.

Q: What is the difference between quartz glass and normal glass?

A: The difference between quartz glass and ordinary glass: quartz is crystal and glass is amorphous solid. The main components of ordinary glass are sodium silicate, silicon dioxide, and calcium silicate, while the main component of quartz glass is silicon dioxide.

Q: What is quartz glass used for?

A: Quartz glass is used in the manufacturing of optical devices, lighting systems, refractory materials, and chemical apparatuses.

Q: Is quartz glass stronger than normal glass?

A: Quartz actually has significantly less mechanical strength than glass (borosilicate). So why does everyone believe it to be stronger? We believe this erroneous thought process is derived from the extreme temperature differentiation (thermal shock) the fused quartz can withstand that borosilicate can not.

Q: What is quartz glass called?

A: Quartz glass is an amorphous solid so it has not a definite heat of fusion. This is due to short range order of molecule while quartz glass is also known as super cooled liquid and isotropic in nature. Suggest Corrections.

Q: Can quartz glass be heated?

A: Quartz glass is highly heat resistant and withstands rapid heating and cooling more than ten times better than ordinary glass. This heat resistance, however, becomes lower as the wall becomes thicker.

Q: What is quartz glass made of?

A: Quartz glass is made by melting natural quartz crystals of exceptional purity with an SiO2 content of 99.9% and allowing the melt to cool down in the shape and dimensions required. The source material has particularly low iron, potassium and sodium oxides, and as a result very low trace element content.

Q: How to clean quartz glass?

A: The fused quartz should be cleaned by placing it in a 7% maximum solution of Ammonium Bifluoride for no more than ten (10) minutes, or a 10% volume maximum solution of Hydrofluoric Acid for no more than five (5) minutes.

Q: Is quartz glass Tempered?

A: Glass made of quartz cannot be tempered as it has an extremely low coefficient of expansion making it resistant to high temperature differences. Fused quartz is natural quartz, made from a mould containing more than 99% quartz sand that melts at a very high temperature.

Q: What is the density of quartz glass?

A: The calculation results of density for the model is approximately 2.25g/cm 3 , which is very close to the actual density of quartz glass (2.2g/cm 3 ).

Q: What are common applications of quartz glass plates?

A: Common applications include laboratory equipment, semiconductor manufacturing, optical components, and high-temperature furnaces.

Q: How is quartz glass made?

Q: Is all glass made of quartz?

A: Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added.

Q: How to tell glass from quartz?

A: Inspect the specimen for air bubbles. If air bubbles are present, it is glass, not quartz crystal. Quartz crystal may contain imperfections, but they are not perfectly round like air bubbles. Perform your own Mohs hardness test.

Q: Is quartz glass strong?

A: In conclusion, both fused quartz and borosilicate are glass and glass-ceramics. Both are susceptible to breaking when involved in accidents causing mechanical stress. The quartz material, however, is over 5x more likely to break than the glass. So please, treat your quartz as carefully as you would your glass.

Q: What is the melting temperature of quartz glass?

A: Approximately 1600 °c
Quartz melts at approximately 1600 °C and forms a tacky liquid. Many silicon-oxygen bonds are broken in the course of melting. Quartz glass is also known as silica glass since it is obtained by melting silica.

Q: What are the properties of quartz glass?

A: The advantages of fused silica or quartz glass include:
Incredibly thermally shock resistant (can be taken from red heat and plunged into water without cracking)
Low coefficient of thermal expansion.
Optical transmission properties from ultra violet to infra red.
Good chemical resistance.
Excellent electrical insulator.
