Raw Materials for Quartz Glass
Natural crystal raw materials
The mineralogy of crystal is quartz，chemical composition is Sio2, it is a transparent quartz crystal. According to the production process of crystal, it can be divided into natural and artificial crystals. According to its particularity and use, it can be divided into piezoelectric crystal, optical crystal, smelting crystal and craft crystal.
Silica raw material
Silica raw material is an important mineral resource widely distributed in nature. It is a general term for mineral raw materials composed of Sio2 as the main chemical component and quartz as the main mineral.
Industrially, bulk silicon raw materials are collectively referred to as silica. The rock types of silica include quartzite, quartz sandstone, meteorite, quartz schist vein quartz and quartz sand.
