What is the reason for the discoloration of alumina ceramic products?

Most ceramic products are white, as is alumina ceramics. But for some reason, after a long period of use, these ceramic products will turn from white castings to light yellow. Is it because the alumina ceramics have changed color?

The reason why the white alumina ceramic gradually turns into pale yellow is because of the changes in its internal composition after sunlight exposure, and this change is irreversible, so the color will also change.

On the other hand, it may be that the alumina ceramic has deliquesed, resulting in the production of hydrated alumina. In fact, not only ceramic products have this characteristic, other materials will also have it, so we can only overcome the discoloration of alumina ceramics by minimizing the influence of external factors.

Regarding alumina ceramics, in addition to clarifying the reasons behind its discoloration, it is also necessary to master some basic principles of using it to make shaft cores to ensure that the products made meet the requirements and can be used normally.

Taking into account the special material, it is necessary to be more careful when designing the alumina ceramic shaft core to reduce unnecessary damage. The main content involved mainly includes the type, size and location of the installation part, the fixing method of the part, the nature, direction, size and distribution of the load; the type and size of alumina ceramic bearing; the rough, manufacturing and manufacturing of alumina ceramic shaft A series of factors such as assembly process, installation and transportation; deformation of the shaft.
