Zirconia ceramic (Zirconium Oxide, or ZrO2), also known as "ceramic steel", combines high hardness, wear and corrosion resistance, and one of the highest fracture toughness values among all ceramic materials.
1. In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their high toughness, high flexural strength, high wear resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel.
Mainly include: Y-TZP grinding balls, dispersing and grinding media, nozzles, ball valve ball seats, zirconia molds, micro-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, golf light bats and other wear-resistant parts at room temperature, etc.
2. In terms of functional ceramics, its excellent high temperature resistance can be used as induction heating tubes, refractory materials, and heating elements. Zirconia ceramics have sensitive electrical parameters.
It is mainly used in the fields of oxygen sensor, solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) and high temperature heating element.
