What Alumina Ceramic Surface Can Be Black?

Alumina ceramics in what aspects are better, but the only bad place is that the glaze is more prone to black phenomenon, and this will affect the normal use of alumina ceramics. And we can do, is to try to find out the reasons for this, and timely and effective solution, so as to carry out a fundamental improvement in the quality of alumina ceramics, but the actual situation is so far, whether there is a good solution in this respect?

After continuous research and test, finally found out the main factors of alumina ceramic glaze blackening, and developed a series of targeted solutions.

The first is the choice of raw materials, the raw materials we speak of here, refers to the raw materials of ceramic alumina, but the raw materials of ceramic glaze, it is not best to choose easy to smoke materials, in order to prevent the sensitivity of the atmosphere to be effectively reduced.

Secondly, at the same time, the temperature of the process should be effectively controlled. The most effective way is the temperature of glaze burning to ensure that it is not higher than the temperature of cermet, so that the phenomenon of glaze blackening can be effectively solved.

Finally, the solution of alumina ceramics in melanin, and the solution of roughness have an effective measure, so the above two points we can try, and choose the most effective solution.
