Quartz Glass Plate Clear Quartz Plate Glass Transparent Uv Quartz Glass Plate

Product Description
transparent uv quartz glass plate,clear quartz plate glass1. high temperature resistance glass can work under 1200°C continuously,and in short time can even work under 1450°C,its softening point is 1650°C,and the melting point is 1650-1800°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 is30 times 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.
