The wear resistance of zirconia ceramic lining bricks is 15 times that of alumina ceramics, and his friction coefficient is only 1/2 of that of alumina ceramics, while the friction coefficient 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 3.6, the density of zirconia ceramics is ≥6, the texture is more delicate, and after grinding and processing, the surface finish is higher, mirror-shaped, extremely smooth, and the friction coefficient is smaller. In addition, the toughness of zirconia ceramics is excellent, which overcomes the inherent brittleness of the ceramics themselves, has higher wear resistance, and greatly prolongs the service life of the product.
