Характеристики
Product Description
Quartz plate/round quartz disc/quartz sight glass discperating temperature is 1200℃ to 1500℃.The softening temperature is 1650°C
,and the melting temperature is
1750-1800°C.
2.Corrosion resistant, Except hydrofluoric acid, quartz glass disc do not react with any acid and base except hydrofluoric acid
.the stability is 30 times of the ceramic,and 150 times of stainless steel .
3.High transmission is 85%-90% for UV-light.
4.Polished surfaces 80/50, 60/40 quality,Clear and clean apperances
5.Electric insulation ,it is 10000 times of usual glass.
