Alumina ceramic is also called al2o3 ceramic or aluminum oxide ceramic, is one of the most widely used technical ceramic materials. Alumina ceramic has a series of advantages such as high strength, good dielectric properties, excellent wear resistance, high temperature resistance and corrosion resistance. It is one of the most hard and wear resistant materials on the earth and can only be machined using diamond tools after sintering. The applied fields of alumina ceramic is very wide, including machinery, electrical, electronics, semiconductor, petroleum, chemical, textile and other industries etc.
