Zirconia Ceramic Zirconia is a material with very high resistance to crack propagation. And its fine grain size enables excellent surface finishes and the ability to hold a sharp edge. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel. Zirconium oxide ceramics are used among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.

In functional ceramics, its excellent high-temperature performance as induction heating tube, refractory material, heating element used. Zirconia ceramics with electrical parameters sensitive, mainly used in oxygen sensors and solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) and high temperature heating index field of.ZrO2 has a higher rate of (N-21^22), add some coloring elements in zirconium oxide superfine powder in (V2O5, MoO3, Fe2O3 etc.), it can be made of colorful translucent polycrystalline ZrO2 material, like natural stones as bright and colorful flashing light, can be made into various decorations. In addition, the zirconia thermal barrier coating, catalyst carrier, medical, health care, refractory materials, textile and other fields are widely used.
