1.high temperature resistant, High pressure cut quartz tube for tube furnace 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 tube 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.
