Has now been used in high-performance fiber-optic communications materials is the main raw material for silicon dioxide. Generally higher than that of pure quartz crystal can be used to manufacture glass. Quartz glass commonly used in the manufacture of high temperature resistant chemical equipment. Crystal used to manufacture important components of the electronics industry, optical equipment, is also used to make high-level industrial and optical films and so on. Features Specifications: sio2
