The main raw material of 99 alumina ceramics is: 99% pure alumina. The temperature change range of its bending strength is small, and the fracture toughness gradually increases with the decrease of temperature. The thermal conductivity of 99 alumina is much lower than that of stainless steel. So what are the properties of 99 alumina ceramics and its applications?
1. 99 alumina ceramicsIncluding positioning posts and shaft rods, Components such as piston rods, bearing sleeves and ceramic seals on mating end faces, which are mainly used in chemical and physical conditions, are good corrosive media. These components can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products. Ceramic injection molding and ceramic grinding are usually used to produce a variety of complex components with strict surface finish and flatness requirements. These components are Frequently used in water resources management, medical, automotive, telecommunications and home appliance applications, etc.
2. Properties of 99 alumina ceramics
99 alumina ceramic has a high melting point, high hardness and high mechanical strength, and can withstand a maximum temperature of 1800°C.The thermal shock stability is reduced due to the increase in the relatively large thermal expansion coefficient. 99 alumina ceramic is an electrical insulating material with high resistivity. It also has good chemical stability, so alumina has good corrosion resistance. , 99 alumina ceramic is insoluble in water, only slightly soluble in strongAcid and alkaline aqueous solutions. 99 alumina ceramic is a mature engineering ceramic. It provides excellent electrical insulation properties, high hardness and wear resistance but relatively low strength and Fracture toughness.
