Zirconia is a kind of white powder inorganic compound, with high hardness, high strength, high melting point, corrosion resistance and other excellent physical and chemical properties. It has a variety of crystal phases, such as monoclinic phase, cubic phase and trigonal phase, and different crystal phases have different physical and chemical properties. Zirconia is widely used in high temperature ceramic materials, coatings, zirconia ceramic ball milling media and biomedical materials. In terms of refractories, zirconia has a melting point of up to 2700 ° C and is an excellent refractory. In addition, zirconia is also used in the preparation of high-performance ceramic parts, electronic devices and thermal barrier coatings.
