Zirconia Ceramic And Alumina Ceramic

 

Zirconia ceramic and alumina ceramic are the most widely used materials in the field of advanced ceramics. They can be used as abrasives.

So Zirconia Ceramic And Alumina Ceramic,which has better wear resistance?

The hardness of natural alumina is indeed very high. However, what we commonly use is artificial alumina ceramics. This is a very complex material and sintered by artificial ingredients. People will not call it corundum.Alumina ceramics can be divided into 95alumina, 97alumina, 99alumina and so on.

Zirconia ceramic also presents interesting variations in material purities. The hardness of alumina ceramics of different purities is also different.

From this, we can see that the hardness between zirconia ceramics and alumina ceramics can be said to be comparable. However, the density of zirconia ceramics is about 40% higher than that of alumina.

If the grinding medium needs to work under centrifugal force, then the choice of zirconia ceramic is more suitable. This is because of its high density, which can produce greater shear force under the same conditions. It is more effective to improve the efficiency of grinding, making zirconia ceramics the preferred choice in such scenarios.

However, if alumina ceramics are used for grinding in other cases where centrifugal force is not used to achieve grinding, the wear resistance of alumina ceramics will be better, though zirconia ceramic might still be an alternative depending on the specifics.
