Product Description
>Silicon: 99.99%
High temperature resistance
Quartz glass softening temperature is about 1730 C, can be prolonged use at 1100 C, short-term maximum temperature up to 1450 C.
Corrosion resistance
In addition to hydrofluoric acid, quartz glass almost does not react with other acids in chemical reaction, its acid capacity is 30 times that of ceramic, 150 times that of stainless steel, especially in the chemical stability at high temperatures, which  any other engineering materials are unable to match.
Good thermal stability
Thermal expansion coefficient of quartz glass is extremely small, it can withstand severe temperature changes.When quartz glass is heated to about 1100C, it will not burst into the water at room temperature.
Good light transmission properties
Quartz glass have better light transmission properties in entire spectral bands from ultraviolet to infrared,visible light transmittance of 93% or more, particularly in the UV spectral region, the maximum transmittance of up to 80 or more.
Good electrical insulation properties
Resistance value of quartz glass is equivalent to one million times that of ordinary glass, it is an excellent electrical insulating materials, even at high temperatures it also have good electrical properties.Quartz glass has above excellent physical and chemical properties, it is widely used in electric light sources, semiconductors, optical communications, military, metallurgy, building materials, chemical, mechanical, electrical, environmental protection and other fields.
