1. Product Description

1. high temperature resistant, Quartz Slab Or Optical Quartz Glass Plate Or Quartz Substrate,

Fused Quartz Glass can work under 1200°C continuously,and in short time can even work

under 1450°C,its softening temperature is 1650°C,and the melting temperature is 1750-1800°C.

2. Corrosion resistant, Except hydrofluoric acid, Quartz Plate Of Optical Grade do not react with

any acid and base except hydrofluoric acid.the stability is

30 tims of the ceramic,and 150 times of stainless steel .

3. Excellent thermal shock stability

4. High transmission to 85%

5. Electric insulation ,it is 10000 times of usual glass
