The High Purity Zirconia Ceramic Tile as Wear Lining Plate for Mining Equipment  is 15 times that of alumina ceramic, and its friction coefficient is only 1 /2 of alumina ceramic, while the friction coefficient of alumina ceramic itself is very low. The density of zirconia ceramics is higher than that of alumina ceramics, the density of alumina ceramics is 3.6, the density of zirconia ceramics is ≥ 6, and the texture is more delicate. After grinding, the surface finish is higher, mirror like, extremely smooth and the friction coefficient is smaller. In addition, zirconia ceramics have excellent toughness, overcome the inherent brittleness of ceramics, have higher wear resistance and greatly prolong the service life of products.
