Quartz Crucible (SiO2)
Quartz Crucible
The quartz crucible is divided into transparent and opaque. The semi-transparent quartz crucible is made by arc melting method of pulling monocrystalline silicon, which is an indispensable raw material for developing large-scale integrated circuits in the semiconductor industry. The quartz crucibles have the advantages of high purity, strong temperature resistance, large size, high precision, and good thermal insulation.
