The main chemical composition of quartz crucible is SIO2, which has the advantages of high purity, strong temperature resistance, large size, high precision, good insulation, energy saving, stable quality and so on. It has a very wide range of applications, such as semiconductor, photovoltaic solar energy, chemical industry and so on.
The thermal stability of quartz crucible is very good, it can be directly placed on the flame heating, its use temperature can reach 1450 degrees, quartz crucible is divided into transparent and opaque, the opaque quartz crucible that is produced by arc method is essential basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuit .
