Alumina ceramics are divided into various types such as 95 alumina, 998 alumina, 995 alumina, etc. due to their different alumina content. 99 alumina ceramic is a kind of high purity, and its mechanical properties will be stronger. Do you know the characteristics and application of 99 alumina ceramics? The following will be introduced by Pintejin Ceramics Factory about the characteristics of 99 alumina ceramics. and applications.

Before introducing the characteristics of 99 alumina ceramics, first understand the 99 alumina ceramics. 99 alumina ceramic materials are often used in chemical and physical grinding environments, especially high-purity alumina is a very good material for the production of wear-resistant components.

99 alumina ceramic positioning column and other ceramic parts include shafts, pistons, bearings and matching face seals. They are mainly used in chemical and physical conditions and are good corrosive media. These components can be used in the manufacture of circulating pumps, reciprocating pumps and resonator supported products. Usually ceramic injection molding and precision grinding can produce a variety of complex components with stringent surface finish and flatness requirements. These components are frequently used in water management, medical, automotive, telecom and appliance applications. Properties of 99 Alumina: 99 Alumina has a high melting point, high hardness and high mechanical strength, although the mechanical strength temperature is reduced to over 1000°C. The thermal shock stability decreases due to the relatively large increase in the thermal expansion coefficient. 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. Application of 99 alumina ceramics: Alumina is the most mature industrial ceramics, it provides excellent electrical insulation properties, with high hardness and wear resistance but relatively low strength and fracture toughness, so it is also called wear-resistant ceramics.
