Alumina ceramic applications

- Jul 24, 2019-

Alumina porcelain has high melting point, high hardness, high strength, and has good chemical resistance and dielectric properties. However, it has large brittleness, poor impact resistance and poor thermal shock resistance, and cannot withstand drastic changes in ambient temperature. It can be used to manufacture furnace tubes, linings of high-temperature furnaces, spark plugs of internal combustion engines, etc. It can also manufacture cutting tools with high hardness, and it is also a good material for manufacturing thermocouple insulating sleeves.
