What are the properties of quartz glass?

        1. 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 high temperature can reach 1450 °C in a short time.

        2. Corrosion resistance Except for hydrofluoric acid, quartz glass hardly reacts chemically 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. No other engineering material can match.

        3. Good thermal stability Quartz glass has a small thermal expansion coefficient, and quartz glass can withstand severe temperature changes. Quartz glass will not burst when heated to about 1100 ℃.

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

        5. Good electrical insulation performance The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is a better electrical insulation material and has good electrical performance even at high temperatures.
