Zirconia ceramic

The wear resistance of zirconia ceramics The lining is 15 times that of alumina ceramics, and its coefficient of friction is only 1/2 of that of alumina ceramics, while the coefficient of friction of alumina ceramics itself is very low. The density of zirconia ceramics is higher than that of alumina ceramics. The density of alumina ceramics is 3.6g/cm3, and the density of zirconia ceramics is 6g/cm3. The texture is more delicate. After grinding, the surface finish is higher, up to more than 9. It is mirror-shaped, very smooth, and has a small coefficient of friction. In addition, zirconia ceramics have excellent toughness, overcome the inherent brittleness of ceramics, have higher wear resistance, and greatly extend the service life of the product.
