Quartz Tube Large Diameter Quartz Tube Quartz Glass Tube

Product Description
large diameter high pressure quartz tube resista1. 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 tube 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.
