Customizable zirconia ceramic arms for semiconductors

Short Description:

Zirconia ceramic

Zirconium oxide, also called Zirconia, is an extremely tough technical ceramic with a hardness of >9 Mohs.Zirconia has the highest strength and fracture toughness at room temperature among all the advanced ceramic materials,In addition to withstanding attacks from molten metal, organic solvents, strong acids, and strong alkalis, so zirconia ceramic parts are always used in various severe service conditions.


Product Detail

Product Tags

Zirconia is a material with high mechanical strength and fracture toughness at room temperature. Our zirconia (ZrO2) is added with 3mol%Y2O3 partial stable zirconia (PSZ). Because the particle diameter of PSZ material is small, it can be processed with high precision, and its application in precision machining parts such as molds is expanding. In addition, can also be used for industrial tools, optical connector parts and crushing equipment medium. The high fracture toughness of PSZ can be used to make special springs, and it is also widely used in domestic ceramic knives, slicer and other parts.
