Features:

1, high temperature. Quartz glass softening point temperature is about 1730 , can be at 1100 under prolonged use, short-term maximum temperature up to 1450.
2, corrosion-resistant. In addition to hydrofluoric acid, the quartz glass is almost non-acid substance with other chemical reactions, its acid capacity is 30 times ceramic, stainless steel 150 times, especially in the high temperature chemical stability, is in any other engineering materials can not be match.
3, good thermal stability. Coefficient of thermal expansion of quartz glass, is extremely small, able to withstand drastic temperature changes, quartz glass, heated to 1100 or so, the water will not burst into the room temperature.
4, transmission performance is good. Quartz glass in the ultraviolet to infrared spectral bands have a good overall light transmission properties, visible light transmittance of 93% or more, especially in the ultraviolet spectral region, the largest transmittance of up to 80 or more.
5, good electrical insulation properties. The 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 good electrical properties. With the above-mentioned quartz glass, excellent physical and chemical properties, so it is widely used in electric lighting, semiconductors, optical communications, military, metallurgy, building materials, chemical, mechanical, electrical and environmental protection fields.
