High temperature alumina ceramic refractory laboratory assay crucible
Alumina crucible is a kind of ceramic vessel sintered at high temperature. It is often used for chemical test and material smelting at high temperature. The alumina crucible itself has a very high melting point and can withstand extremely high temperatures. The melting point is usually around 2050C, but there are some high quality alumina crucible melting point above 2300C. This is because alumina has excellent high temperature resistance and chemical stability, and can be used in extreme environments. In the laboratory, alumina crucible is usually used to melt high melting point metals, ceramics, glass and other materials, to carry out chemical reactions at high temperatures, or to carry out sintering tests. In addition, alumina crucible is also widely used in electronics, metallurgy, chemical, pharmaceutical and other industries.
