JGS2 optical quartz glass transparent ultraviolet glass flat window high-temperature resistant glass

Quartz glass is a single component glass material made by melting silicon dioxide (SiO2), with a SiO2 content of ≥ 99.98% and a total content of Fe, Al, Ca, Mg, k, Na, Ti, Li, Ni, Cu, B, Cr ≤ 45ppm.

Quartz glass has extremely low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best ultraviolet spectral transmission performance, visible light transmission and near-infrared spectral transmission performance, and has higher mechanical properties than ordinary glass. It is widely used in semiconductor technology, integrated circuit manufacturing, optical fiber communication, laser technology, Space technology, optical industry Electric light, semi conductive communication device, Optical instrument, laboratory instrument, electrical equipment, medical equipment and high-temperature and corrosion resistant chemical instrument, chemical industry, electronics, metallurgy

Characteristics of quartz glass:

1. Corrosion resistance

Except for hydrofluoric acid, quartz glass hardly undergoes chemical reactions with other acid substances, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially at high temperatures, its chemical stability is unmatched by any other engineering material.

2. High temperature resistance

The softening point of quartz glass is 1730 degrees Celsius, and the annealing point is 1250 degrees Celsius. It can be used for a long time at 1100 degrees Celsius, with a maximum temperature of 1450 degrees Celsius for short periods of time.

3. Good thermal stability

The expansion coefficient of quartz glass is extremely small, 5.4 * 10-7, and can withstand severe temperature changes. When heated to 1100 degrees Celsius, quartz glass will not explode when placed in room temperature water.

4. Good electrical insulation

The resistance value of quartz glass is 10000 times that of ordinary glass, making it an excellent electrical insulation material with good electrical properties even at high temperatures.

Good transparency

Quartz glass has good transmittance throughout the entire spectral range from ultraviolet to infrared, with a visible light transmittance of over 92%, especially in the ultraviolet spectral region, with a maximum transmittance of over 80%.

6. Quartz glass is an acid material. When it is used at high temperature, contact with alkaline substances (such as water glass, asbestos, potassium sodium compounds, etc.) should be strictly avoided. Otherwise, its crystallization resistance will be greatly reduced. 2. Tensile strength (Mpa):~50

3. Inflection resistance: 60-70
