Zirconia Ceramics (ZrO2) especially Yttria Stabilized Zirconia Ceramics (Y-PSZ) is a commonly used technical ceramic material. It has relatively high fracture strength among all ceramic materials, with the addition of high hardness and low friction coefficient, it is usually used for structural ceramic components. Its thermal expansion coefficient is similar to steel, so it can be jointed to steel parts. Besides, it has excellent corrosion resistance and low thermal conductivity.
Typical applications include ceramic valve components, ceramic grinding&milling media, ceramic knife blades for various using, mechanical liners or bearing balls etc.
