Zhongci Quartz Crucible High Temperature Resistance Fused Silica Crucible for Melting Ceramic Crucible Graphite Crucible
Quartz ceramic crucible, full name of high-purity fused silica ceramic crucible, is a ceramic crucible made of high-purity fused silica. In general, its shape is mainly square and cylindrical. Among them, the square high-purity quartz crucible is used in the polysilicon ingot casting link as a container for polysilicon chemicals and long crystals; the round high-purity quartz crucible is used in the single crystal pulling link in the monocrystalline silicon high-purity fused silica is widely used in the glass deep processing industry, metallurgy industry, electronics industry, chemical industry, aerospace industry and other fields due to its fine structure, low thermal conductivity, small thermal expansion coefficient, high dimensional accuracy of finished products, high temperature deformation, good thermal shock stability, good electrical performance, good chemical resistance and other characteristics.
