Ceramic part

 

The mainly material of the ceramic part include:alumina ceramic,zirconia ceramic,silicon carbide and so on.

Which is harder? Silicon carbide or zirconia ceramic?

The hardness of silicon carbide is 8.5 on the Mohs scale, and zirconia is above 9 on the Mohs scale, second only to diamond.

Which is more wear-resistant, zirconia or alumina?

Zirconia ceramic hardness ≥HRA9, second only to the hardness of diamond, and the surface smooth friction coefficient is small, wear resistance is very ideal, especially in high temperature oxidizing medium or corrosive medium, zro2 material performance is much superior than alumina ceramics.

How many degrees of high temperature can zirconia ceramics withstand?

Zirconia ceramics come in many grades of varying purity. High temperature resistance is not only a matter of melting point, depending on the composition, higher energy to more than 1400 degrees. Theoretically, high and low temperature conditions can maintain the original characteristics.

What are the molding processes of zirconia ceramics?

At present, there are many zirconia molding processes, including dry press molding, hot die casting molding, grouting molding, injection molding, isostatic press molding, etc., among which isostatic pressing ceramic parts are better.

Is the wear resistance of zirconia ceramics related to pores?

The more pores in the ceramic part, the lower the density and the less wear-resistant the product. Conversely, fewer pores indicate higher density and less likely to wear out the product.
