Comparison of advantages of zirconia ceramic and alumina ceramic materials

Comparison of ceramic toughness:
The toughness of zirconia ceramics is four times that of alumina ceramics. At the same time, zirconia will fall freely from a height of one meter, but there will be some gaps. The alumina will break.
Density comparison:
The density of zirconia ceramics is twice that of alumina ceramics, and the compressive performance of zirconia ceramics is better.
Friction coefficient comparison:
The friction coefficient of zirconia ceramic is only 1/2 of that of alumina ceramic, while the friction coefficient of alumina ceramic itself is very low. In the actual use process, more attention should be paid to the elastic wear and hard wear. The specific wear-resistance of the material depends on the actual use.
Density contrast:
The density of zirconia ceramic structural parts is higher than that of alumina ceramic. The density of alumina ceramic is 3.5, and the density of zirconia ceramic structural parts is 6. The texture is more exquisite. After grinding, the surface finish is higher, up to ▽ 9 or more, which is mirror, extremely smooth, and the friction coefficient is smaller.
Surface finish contrast:
Zirconia ceramic structural parts have a higher surface finish, mirror shape, extremely smooth, and less friction with the mesh, which can further improve the service life of the mesh, greatly reduce the mesh consumption, reduce the paper mesh current, and reduce the power consumption. In addition, zirconia ceramic structural parts have excellent toughness, overcome the inherent brittleness of ceramics, have higher wear resistance, greatly prolong the service life of products, and significantly improve the quality of paper.
Zirconia ceramic structural component is a very important structural ceramic developed recently, which is second only to alumina ceramic. Because of its good properties (such as its fracture toughness is higher than that of alumina ceramics), zirconia ceramic structural parts have attracted more and more attention.
