The same as the description of excellent physical and chemical properties. Anti-corrosion : In addition to hydrofluoric acid, is an almost non-acid and other substances a chemical reaction, especially in the high temperature chemical stability, is in any other engineering materials can not be compared. Thermal stability : The thermal expansion coefficient of quartz glass, is extremely small , able to withstand drastic temperature changes. Softening point temperature of about ***0 degrees Celsius, ***0 degrees Celsius in a long time use, short-term maximum temperature up to ***0 degrees Celsius. Transmittance good performance : quartz glass in the entire ultraviolet to infrared spectral bands have a good light transmission properties, visible light transmittance of *3% or more , especially in the ultraviolet spectral region, the largest up to *0% or more transmittance. Good electrical insulation properties : resistance of quartz glass is equivalent to ten thousand times the normal glass is an excellent electrical insulation materials, even at high temperature also have good electrical properties
