Temperature : softening point temperature of about 1730 degrees Celsius ,1100 degrees Celsius in a long time use ,short-term maximum temperature up to 1450 degrees Celsius ;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 galss ,is extremely small ,able to withsand drastic temperature changes ;Transmittance good performance :quartz glass in the entire ultraviolet to infrared spectral bands have a good light transmission properties, visible light transmittance of 93% or more ,especially in the ultraviolet spectral region ,the largest up to 80% 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 temperatures also has goog electrical properties
