Why Do Alumina Ceramic Products Change Color?

Time：202021-10-19

Most of the ceramic products are basically white, and of course the same is true for alumina ceramics. But for some reason, these ceramic products will turn from white castings to light yellow after a long time of use. Is the alumina ceramic discolored? Next, the editor will tell you why the alumina ceramic discolors?

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

On the other hand, it is possible that the alumina ceramics have deliquesed, resulting in the production of hydrated alumina. In fact, not only ceramic products have this characteristic, but also other materials, 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 produced 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 the alumina ceramic bearing; the rough, manufacturing and manufacturing of the alumina ceramic shaft .A series of factors such as assembly process, installation and transportation; deformation of the shaft.

It must be designed according to the specific requirements of the alumina ceramic shaft, but on the premise of saving materials and reducing weight, try to use the cross-sectional shape of equal strength and large cross-sectional coefficient; and adopt various types of reducing stress concentration and increasing strength. Structural measures to further ensure the quality and performance of the product.
