Today, the ceramic industry has developed rapidly in all walks of life. Industrial ceramics have been widely used in many fields in recent years due to their superior characteristics. Among them, zirconia ceramics and alumina ceramics are the most common. The characteristics of the two types of ceramics have their own advantages. Many companies do not know how to choose zirconia ceramics and alumina ceramics. Today, Mingxing Ceramics Factory will introduce you:
1. Density comparison
The density of zirconia ceramics is twice that of alumina ceramics. In contrast, zirconia has better compression resistance.
2, the 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, the texture is more delicate, after grinding, the surface finish is higher, and it is mirror-like , Very smooth, the friction coefficient is smaller.
3. Comparison of surface finish
Zirconia ceramic structural parts have a higher surface finish, mirror-like appearance, extremely smooth, and less friction with the net, which can further increase the service life of the net, greatly reduce the net consumption, reduce the current of the net part, and reduce the power consumption . In addition, the toughness of the zirconia ceramic structural parts is excellent, overcoming the inherent brittleness of the ceramic itself, the wear resistance is higher, the product service life is greatly extended, and the paper quality is obviously improved.
4. Comparison of ceramic toughness
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, zirconia can fall freely from a height of one meter, but there will be some gaps. The alumina will be broken.
5. Comparison of friction coefficient
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 must be given to the elastic and hard wear. The specific kind of material can wear depends on the actual use.
Zirconia ceramic structural parts is a very important structural ceramic that has been developed recently, second only to alumina ceramics. Due to some of its good properties (such as its fracture toughness is higher than alumina ceramics), zirconia ceramic structural parts are more and more valued by people.
