In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of their high toughness, high bending strength, high wear resistance, excellent thermal insulation performance, and thermal expansion coefficient close to steel. It mainly includes Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve sockets, zirconia molds, miniature fan shafts, optical fiber pins, optical fiber sleeves, wire drawing dies and cutting tools, wear-resistant knives, clothing buttons, watch cases and straps, bracelets and pendants, ball bearings, light golf ball bats and other room temperature wear-resistant components.
