1. High temperature resistance glass can work under 1250°C continuously,and in short time can even work under 1450°C, its softening point is 1730°C.
2.Quartz glass will not reat chemically with acid except hydrofluoric.Acid-stable is 30 times of ceramic and 150 times of stainless steel.Es-pecially chemical stability is incomparable at low temperature.
3.Electric insulation.
4.Excellent thermal shock stability
5.High transmission above 85%
6.Widely used in semiconductor , lighting and electric heating industries.
