Quartz ceramic crucible is a ceramic crucible made of high-purity fused silica. In general, its shape is mainly square and cylindrical. The full name is high-purity fused silica ceramic crucible.
Among them, square high-purity quartz crucibles are used in the polycrystalline silicon ingot process, serving as containers for polycrystalline silicon materials and crystal growth; A circular high-purity quartz crucible is used in the process of pulling single crystals in single crystal silicon.
High purity fused silica is characterized by fine structure, low thermal conductivity, small thermal expansion coefficient, high dimensional accuracy of finished products, high temperature deformation resistance, good thermal shock stability, good electrical performance, and good chemical resistance,
Therefore, it has been widely used in the glass deep processing industry, metallurgical industry, electronic industry, chemical industry, aerospace and other fields.
