Application:
1. High temperature resistance glass can work under 1200°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.
