Alumina is the most common advanced precision ceramic material, and it is also a relatively traditional material. As an excellent ceramic material, high-purity alumina ceramics have been widely used in many industries. The material has excellent properties in terms of electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Alumina ceramics have excellent dielectric strength, high-frequency loss is relatively small but high-frequency dielectric strength is good, followed by alumina ceramic raw materials with temperature resistance, small linear expansion coefficient, high impact toughness and heat conduction Good rate and other characteristics, alumina ceramics have the characteristics of chemical corrosion resistance and molten metal resistance, but it is not known that alumina ceramics are flame retardant, stainless steel is strong and not easy to be destroyed, which have good characteristics that other materials and metal composite materials cannot be compared.

Alumina ceramic is a very wear-resistant precision ceramic material, which is widely used in various industries. The main molding methods of alumina ceramic products are: dry pressing, isostatic pressing, injection molding and casting. Different product shapes, sizes, complex shapes and precision products require different molding methods. Alumina ceramic products sintered at high temperature can only be processed by diamond grinding process. Alumina ceramic materials have extremely high hardness and wear resistance, strong corrosion resistance, high temperature resistance, corrosion resistance and biological inertness. In addition, alumina after high-temperature sintering can be highly polished and is widely used in many fields.

Alumina ceramics have the advantages of low thermal expansion, high thermal conductivity, high mechanical strength and good wear resistance. The use of alumina ceramics is to resist the erosion of gold and slag, and can also be used as special refractory materials, wear-resistant parts and tool materials in the machinery industry, and insulators in the electronics industry and other industries.
