What are the advantages and uses of 99% alumina ceramics?

99 alumina ceramics have the advantage of having a very high melting point, high hardness, and high mechanical strength, although the mechanical strength temperature is reduced to more than 1000°C.

Due to the increase of relatively large thermal expansion coefficient, so the thermal shock stability is reduced, 99 alumina ceramic advantage is a kind of electrical insulation material, with high resistivity.

It also has good chemical stability of alumina, so good corrosion resistance, 99 alumina is insoluble in water, only slightly soluble in strong acid and alkaline aqueous solution.

Ceramic injection molding and precision grinding are commonly used to produce a wide variety of complex components with strict surface finish and flatness requirements.

These components are commonly used in water management, medical, automotive, telecommunications and appliance applications. Alumina is the most mature engineering ceramics, it provides excellent electrical insulation properties, high hardness and wear resistance but relatively low strength and fracture toughness.
