Will zirconia ceramics gradually replace alumina ceramics in the industry?

Alumina ceramics have been widely used in recent years, but due to the rise of zirconia ceramics, the two ceramics are now gradually evenly divided, and each has its own advantages. The following Pintejin Ceramics Factory will compare them.

Ceramic toughness comparison:

The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, when zirconia is dropped freely from a height of one meter, there will be some gaps and the alumina will be broken.

Density comparison:

The density of zirconia ceramics is twice that of alumina ceramics, and the compressive properties of zirconia are better.

Zirconia ceramic parts Friction coefficient comparison:

The friction coefficient of zirconia ceramics is only 1/2 of that of alumina ceramics, while the friction coefficient of alumina ceramics itself is very low. In actual use, more consideration should be given to elastic wear and hard wear. The specific material that can be worn depends on the actual use.

Density comparison:

The density of zirconia ceramic structural parts is higher than that of alumina ceramics, the density of alumina ceramics is 3.5, the density of zirconia ceramic structural parts is 6, and the texture is more delicate. 9 or more, it is mirror-like, extremely smooth, and has a smaller friction coefficient.

Surface finish comparison:

Zirconia ceramic structural parts have higher surface finish, mirror-like, extremely smooth, and less friction with the mesh, which can further improve the service life of the mesh, greatly reduce mesh consumption, reduce paper mesh current, and reduce electricity consumption . In addition, the toughness of the zirconia ceramic structure is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, greatly prolongs the service life of the product, and significantly improves the quality of paper.

Zirconia ceramic structural parts are recently developed as a very important structural ceramics, second only to alumina ceramics. Because of some 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.
