Product Description

General introduction:Quartz flakes are usually smelted and cut and ground from quartz, and their silica content can reach more than 99.99%. The hardness is Mohs 7, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance. Usually colorless and transparent, the visible light transmittance is more than 85%.

Product Description:The optical properties of the quartz sheet have its own uniqueness. It can not only transmit far ultraviolet rays, which is the best of all ultraviolet transmissive materials, but also transmit visible light and near-infrared spectrum. Because quartz glass has high temperature resistance, extremely small thermal expansion coefficient, good chemical stability, bubbles, stripes, uniformity, and birefringence comparable to general optical glass, it is a high-stability optical coefficient working in various harsh occasions. Essential optical material.

Compared with ordinary silicate glass, transparent quartz glass has excellent transmission performance in the whole wavelength head. In the infrared region, the spectral transmittance is larger than that of ordinary glass; in the visible region, the transmittance of quartz glass is also relatively high. In the ultraviolet spectral region, especially in the short-wave ultraviolet region, the spectral transmission is much better than other glasses. Spectral transmittance 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. Therefore, the transmittance of quartz glass is generally not more than 92%. The scattering of quartz glass is relatively small and can generally be ignored.

Quartz sheets can be divided into three categories according to their optical properties:
1. Far UV Optical Quartz Glass JGS1:
Transparent in the ultraviolet and visible spectral range; no absorption band in the 185-250nm band; strong absorption band in the 2600-2800nm band; non-luminescent, stable light radiation.

2. UV optical quartz glass JGS2:
Transparent in the ultraviolet and visible spectral range; no absorption band in the 200-250nm band; strong absorption band in the 2600-2800nm band; non-luminescent, stable optical radiation.

3. Infrared optical quartz glass JGS3:
Transparent in the visible and infrared spectral range; no obvious absorption band in the 2600-2800 nm band.

Quartz flake is a special industrial technical glass made of silica, which is a very good basic material.

Quartz flakes have a series of excellent physical and chemical properties:
1. High temperature resistance. The softening point temperature of quartz glass is about 1730°C, it can be used for a long time at 1100°C, and the maximum use temperature in a short time can reach 1450°C.

2. Corrosion resistance. Except for hydrofluoric acid, quartz glass hardly reacts with other acid substances, its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperature, which is unmatched by any other engineering materials. comparable.

3. Good thermal stability. The thermal expansion coefficient of the adaptable glass is extremely small, and it can withstand severe temperature changes. It will not burst when the quartz glass is heated to about 1100 ° C and placed in normal temperature water.

4. Good light transmission performance. Quartz sheets have good light transmittance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach above 80.

Product applications:
The formation of quartz flakes is the result of the high viscosity of its melt at high temperature. It is used in the manufacture of semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and high temperature and corrosion resistant chemical instruments, chemical industry, electronics, metallurgy, building materials and national defense industries very broad.
