Application of Alumina (Al2O3) Ceramics

Alumina (Al2O3) ceramics have good comprehensive properties and are widely used in application at present.Because it is rich in raw material and has the features of high hardness,strength,higher melting point ,high resistivity,lower cost ,proper surface activity,great adhesion and resistance to heat shocks.

At present ,Al2O3 is the main material of ceramic substrate.The hardness of alumina (Al2O3) ceramics of is second only to diamond.Compared with steel and stainless steel,it is far more better in the wear resistance.
