Zirconia ceramics are white, yellow or gray when containing impurities, generally contain HfO2, not easy to separate.

Application 

It is widely used in structural ceramics and functional ceramics because of its advantages of high toughness, high bending strength, high wear resistance and excellent thermal insulation performance. In terms of structural ceramics, there are mainly: Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan axis, fiber optic pins, fiber optic sleeves, wire drawing dies and cutting tools, wear-resistant Knives, clothing buttons, watch cases and straps, bracelets and pendants, ball bearings, light golf clubs and other room temperature wear-resistant parts. In terms of functional ceramics, its excellent high temperature resistance is used as induction heating tubes, refractory materials, and heating elements. In addition, zirconia is widely used in thermal barrier coatings, catalyst carriers, medical treatment, health care, refractory materials, textiles and other fields.
