Alumina ceramics are divided into many types due to their different alumina content, such as 75 alumina, 85 alumina, 95 alumina and so on. 99 alumina is a kind of very high purity, and its mechanical properties will be stronger.

99 alumina ceramic materials are usually used in chemical and physical grinding environments, especially high-purity alumina is a very good material for the production of wear-resistant components.
These components include shafts, pistons, bearings and mating face seals. They are mainly used in chemical and physical conditions and are good corrosive media. These components can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products.
Generally, ceramic injection molding and precision grinding can be used to produce a variety of complex components with strict surface finish and flatness requirements. These components are frequently used in water management, medical, automotive, telecommunications and home appliance applications.
99% alumina properties:
99 alumina has a high melting point, high hardness and high mechanical strength, although the mechanical strength temperature is reduced to more than 1000 °C.
Due to the relatively large increase in the coefficient of thermal expansion, the thermal shock stability is reduced.
99 alumina is an electrical insulating material with high resistivity. It also has good chemical stability of alumina, so it has good corrosion resistance.
99 alumina is insoluble in water, only slightly soluble in strong acid and alkaline aqueous solutions.
99% of alumina applications:
Alumina is the most mature engineering ceramic. It provides excellent electrical insulation properties, high hardness and wear resistance but relatively low strength and fracture toughness.
