What Are The Differences Between Zirconia Ceramics And Alumina Ceramics?

Time: 2021-09-24   Writer: Mingrui Ceramics
Zirconia ceramics and alumina ceramics, as the "leading" among the new ceramic materials, have many excellent properties, so they are widely used. People often ask what is the difference between zirconia ceramics and alumina ceramics? So what is the difference between the two? Mingrui Ceramics will answer for you. 
 
Zirconia Ceramic and Alumina Ceramic Products
 
Mingrui Ceramics is an enterprise and factory specializing in the production of zirconia ceramics and alumina ceramic structural parts. It mainly produces reinforced zirconia ceramic rods, ceramic tubes, ceramic shafts, ceramic plates, ceramic sleeves, ceramic valves, ceramic plungers and Ceramic arms, Mingrui ceramic structural parts are widely used in high-end fields such as instrumentation, food and medicine, solar photovoltaic, mechanical hardware, laser semiconductor, petrochemical, automotive and military industry, aerospace and so on.
 
Then we first compare the advantages of zirconia ceramics and alumina ceramics.
 
Ceramic toughness comparison:
 
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, the free fall of zirconia from a height of one meter will only cause some cracks in the alumina to break.
 
Density comparison:
 
The density of zirconia ceramics is twice that of alumina ceramics. In contrast, zirconia has better compression resistance.
 
Comparison of friction coefficient:
 
The friction coefficient of zirconia ceramics is only 1/2 of that of alumina ceramics, and the friction coefficient of alumina ceramics itself is very low. In actual use, it is more important to consider the amount of elastic and hard wear. The specific wear resistance of the material depends on the actual use.
 
Density comparison:
 
The density of the zirconia ceramic structure is higher than that of the alumina ceramic. The density of the alumina ceramic is 3.5, and the density of the zirconia ceramic structure is 6, the texture is more delicate. After grinding, the surface finish is higher, up to ▽ Above 9, 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 net, which can further improve the service life of the net, greatly reduce the net consumption, reduce the current of the paper net, and reduce the power 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 the paper. Zirconia ceramic structural parts are a very important structural ceramic newly developed second only to alumina ceramics. Due to some of its good properties (such as its fracture toughness higher than that of alumina ceramics, zirconia ceramic structures have attracted more and more attention.
