✨Quartz glass crucible is a kind of special glass containing only silicon dioxide single component, fine work is clearly visible inside, thickened glass inner wall thickness 2mm, high transparency.

✨Quartz crucble JGS-2 ultraviolet quartz glass: quartz glass produced with quartz raw materials and chlorine oxygen flame contains a few +PPM of metal impurities · There is an absorption peak at 2730NM (light base content 100-200PPM)· There are streaks and star structure it is a good material in the band range of 220-2500 PM
br>✨Quartz glass crucible has high hardening temperature and can be used for a long time. In particular, the chemical stability at high temperatures is unmatched by any other engineering materials. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulation material and has good electrical properties even at room temperature.
