Crucibles are used for melting special glass and non-ferrous metallurgy, as well as for calcining rare earths, high-purity alumina (gem grade), battery materials, etc.
The quartz crucible is a key component of the polycrystalline silicon ingot furnace used in solar cells. As a container for loading polycrystalline silicon raw materials, it needs to work continuously at a high temperature of 1550 degrees Celsius to melt it. Its usage conditions are quite strict, with strict requirements for the purity, strength, microstructure, high-temperature performance, thermal shock stability, and dimensional accuracy of the crucible.
Advantages:
High purity and strength
● Less appearance defects
Good high-temperature performance and thermal shock stability
Advanced production process technology
