Zirconia (ZrO2) Ceramics have the highest toughness and strength at room temperature of all the advanced ceramic materials. At present, it has been widely used in grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant knives, and other room-temperature resistant Grinding parts and so on. Zirconia is widely used in the fields of the thermal barrier layer, catalyst body, medical treatment, health care, textile, and so on.
