Quartz plate is a kind of special industrial technology glass made by melting and cutting quartz. Its main component is high-purity silica (SiO2), and the content is usually as high as 99.99% or more. This material is widely used in many fields because of its unique physical and chemical properties.

1. High hardness

The hardness of quartz plate reaches Mohs 7, which makes it a very durable material. High hardness means it can maintain good integrity and extend its service life when exposed to external pressure or wear.

2. High temperature resistance

The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C, and the maximum temperature for a short time can reach 1450 ° C. This high temperature resistance allows quartz plates to maintain stable physical properties in high temperature environments without deformation or damage.

3. Low coefficient of thermal expansion

Quartz plate has a low coefficient of thermal expansion, which means that its volume changes relatively little when the temperature changes. This property allows the quartz plate to withstand severe temperature changes without bursting, making it particularly suitable for applications where temperature fluctuations are required.

4. Excellent thermal shock resistance

Due to its low thermal expansion coefficient and stable physical structure, the quartz plate exhibits good thermal shock resistance. It can maintain the integrity of the structure even under sharp temperature changes and is not easy to break.

5. Good electrical insulation properties

Quartz plate is an excellent electrical insulating material with high resistivity and breakdown strength. This makes it an important application in the electrical industry, such as the production of electrical insulating components and insulating media in high-voltage electrical appliances.

6. High light transmittance

Quartz plates have good light transmission properties in the entire spectral band from ultraviolet to infrared, with visible light transmittance above 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%. High light transmittance makes quartz plates an ideal material for making optical glass and instruments.

7. Corrosion resistance

Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. This strong corrosion resistance makes quartz plates widely used in the production of chemical instruments, especially in environments that need to withstand corrosive media.

8. Spectral transmission performance

The spectral transmission performance of quartz plates is affected by three factors: reflection, scattering and absorption. The reflection of quartz glass is generally 8%, the ultraviolet region is larger, and the infrared region is smaller, so the transmittance is generally not more than 92%. The scattering of quartz glass is relatively small and can generally be ignored. Spectral absorption is closely related to the impurity content and production process of quartz glass. At the level of transmittance in the band below 200 nanometers, it represents the amount of metal impurity content; the absorption at 240 nanometers indicates the amount of anoxic structure; the absorption in the visible band is caused by the presence of transition metal ions.

Application field

Quartz plates are widely used in many fields because of their excellent physical properties. For example, in the field of optics, quartz plates are used to make optical glass and instruments to assist people in working in poor optical environments. In the production of chemical instruments, quartz plates become ideal materials because of their high temperature resistance and corrosion resistance. In addition, quartz plates are also used in the production of semiconductors, electric light sources, semiconductor communication devices, lasers, laboratory instruments, electrical equipment, medical equipment, and chemical instruments that are resistant to high temperature and corrosion.

Quartz plates play an important role in many fields due to their high purity, high hardness, high light transmittance, high temperature resistance and corrosion resistance.
