Presumably everyone is used for the material of alumina ceramics. Many small partners are not very familiar with it, so let's learn about what materials are alumina ceramics?

Alumina ceramics, alumina (aluminium oxide), chemical formula Al2O3. It is a kind of high hardness compound, it can also be said to be a ceramic material with alumina as the main body. Alumina ceramics have better conductivity

properties, mechanical strength and high temperature resistance. Its melting point is very high, the melting point is 2054 ° C, and the boiling point is 2980 ° C, which can be used as refractory materials, such as crucibles, high temperature furnace tubes, etc. Ionic crystals that can be ionized at high temperatures, often used in the manufacture of refractory materials.

Many new energy and new technology companies have taken advantage of the high hardness of alumina to manufacture corundum ball grinding machines used in the laboratory to grind materials with a hardness smaller than it. With high-purity raw materials and advanced technology, alumina ceramics can also be made transparent, and lamps for high-pressure sodium lamps can be made.
