Alumina ceramics are a type of ceramic material made from alumina as the main raw material through shaping and sintering.
The granular ceramic body densification and the formation of solid material technology method called sintering is to eliminate the void between the particles in the body of the billet, the exclusion of a small amount of gas and impurities organic matter, so that the particles grow together with each other, the formation of a new substance method of burning the heating device used the most widely used electric furnace.
Zirconia，with its molecular formula of ZrO2, is the main oxide of zirconium. Natural minerals containing zirconium mainly include incline zircon and zircon and so on. Zirconia is usually a white odorless and tasteless crystal, insoluble in water, hydrochloric acid and dilute sulfuric acid, chemically stable, and features high hardness, high melting point, high resistivity, high refractive index and low thermal expansion coefficient characteristics, has been widely used in wet-resistant ceramics, refractory materials, machinery, electronics, optics, aerospace, biology, chemistry and other fields. Our common artificial drills and dental implants are also based on zirconia as the main material.
