The performance of quartz glass
Quartz glass is a special industrial technical glass, made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as:
1. High temperature resistance
The softening point temperature of quartz glass is about 1730°C, and it can be used for a long time at 1100°C, and the maximum operating temperature can reach 1450°C in a short time.
2. Corrosion resistance
Except for hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is unmatched by other engineering materials.
3. Good thermal stability
Quartz glass has a small thermal expansion coefficient and can withstand severe temperature changes. Quartz glass is heated to about 1100°C, and it will not burst when placed in water at room temperature.
4. Good light transmission
Quartz glass has good light transmittance in the entire spectrum from ultraviolet to infrared. Visible light transmittance is over 93%, especially in the ultraviolet spectral region, the maximum transmittance is over 80%.
5. Good electrical insulation
The resistance of quartz glass is 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at room temperature.
