Quartz glass plate, as a special industrial technology glass made of high-purity silicon dioxide (SiO ₂), has a series of significant performance characteristics, which make it widely used in multiple industrial fields.

1、 High purity and chemical stability

Quartz glass plates are usually cut and ground from quartz glass, with a silicon dioxide content of over 99.99%. This high purity gives quartz glass plates excellent chemical stability. Except for hydrofluoric acid and concentrated phosphoric acid, quartz glass hardly undergoes chemical reactions with other acidic substances. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, and its chemical stability at high temperatures is unparalleled by any other engineering material. This characteristic makes quartz glass plates widely used in corrosion-resistant chemical instruments and equipment.

2、 High temperature resistance and thermal stability

The softening point temperature of quartz glass is as high as about 1730 ℃, and it can be used for a long time at 1100 ℃, with a short-term use temperature of up to 1450 ℃. This excellent high temperature resistance makes quartz glass plates highly stable in high-temperature environments. In addition, the thermal expansion coefficient of quartz glass is extremely small, at 5.5 × 10 ^ -7/℃, only 1/12 to 1/20 of that of ordinary glass. This characteristic enables quartz glass plates to withstand drastic temperature changes, and even if heated to around 1100 ℃ and quickly placed in room temperature water, they will not explode. Therefore, quartz glass plates have significant advantages in environments that require high temperatures and drastic temperature changes.

3、 Excellent transparency performance

Quartz glass plates have good transparency throughout the entire spectral range from ultraviolet to infrared. The visible light transmittance is over 93%, especially in the ultraviolet spectral region, where the transmittance can reach over 80%. This makes quartz glass plates widely used in the field of optics, such as optical instruments, lasers, etc. At the same time, quartz glass plates can also transmit far ultraviolet spectra, making them the best among all UV transparent materials. This characteristic makes them important in fields such as semiconductor manufacturing and photolithography technology.

4、 Excellent electrical insulation performance

The resistance value of quartz glass is equivalent to ten thousand times that of ordinary glass, making it an excellent electrical insulation material. Even at high temperatures, quartz glass has good electrical properties. This characteristic makes quartz glass plates widely used in fields such as electrical equipment and semiconductor devices.

5、 High hardness and wear resistance

The hardness of quartz glass is Mohs 7, which has high hardness and wear resistance. This makes quartz glass plates less susceptible to damage when subjected to external impact or friction, and has high compressive and tensile strength. Therefore, quartz glass plates have significant advantages in the production of high-precision optical components, semiconductor devices, and other aspects.

6、 Disadvantages and precautions

Although quartz glass plates have many advantages, there are also some drawbacks that cannot be ignored. Firstly, due to the complex manufacturing process and high material costs of quartz glass, its price is relatively high. Secondly, although quartz glass has high hardness and strength, it is still a glass material and therefore has brittleness, making it prone to fracture when subjected to impact or vibration. In addition, quartz glass has high hardness and is difficult to process, requiring the use of special processing equipment and techniques, which increases processing costs and difficulty. Finally, quartz glass plates have a strong adsorption capacity for pollutants and are easily affected by pollutants, leading to a decrease in their performance. Therefore, special attention should be paid to maintaining cleanliness during use and storage.

Quartz glass plates have a series of significant advantages, including high purity and chemical stability, high temperature and thermal stability, excellent transparency, outstanding electrical insulation performance, as well as high hardness and wear resistance. However, its disadvantages such as high price, fragility, difficult processing, and susceptibility to pollutants cannot be ignored. When using quartz glass plates, it is necessary to consider the specific application scenarios and requirements comprehensively.
