1. Heat resisting. The soften point of quartz glass is ***0 degree, can be used long time under ***0 degree. And the highest using temperature can get to ***0 degree in very short time.
?
2. Corrosion resisting. Quartz glass will not react with any acid material except hydrofluoric acid. Its acid resisting ability is *0 times of the ceramic, and **0 times of the stainless steel. Especially for its chemical stability under high temperature is much better than any other engineering materials.
?
3. Good Heat stability. The coefficient of thermal expansion of quartz glass is very small. It can bear exquisite changing of temperature. Heat up quartz glass to ***0 degree, then put into normal temperature water and it will not be broken.
?
4. Capability of pervious to light is better. Quartz glass has better pervious capability in the whole spectral wave band from ultraviolet radiation to infrared. The penetrate rate of visible light is up to *3%, especially in the area of ultraviolet radiation the largest rate is more than *0%.

?
5. Insulated capability of electricity is better. The resistance value of quartz glass is *0 thousand times of common glass what is the best insulated material of electricity, even in high temperature it still has better electric capability.
