Supply Zirconia Ceramic Ring Zro2 Structural Ceramics Zirconia Parts
Zirconia Ceramic ring is made of high purity zirconia material, which is formed by dry pressing or cold isostatic pressing, sintered at high temperature and processed precisely. Zirconia Ceramic ring has the advantages of excellent wear resistance, corrosion resistance, high hardness, low friction coefficient and so on.
Zirconia ceramics also have high fracture toughness, strong bending resistance, and good thermal insulation. It has almost the same thermal expansion capacity as steel. So we can use it in structural ceramics.
