Why does the superior performance of alumina ceramics turn black?

Why does the superior performance of alumina ceramics will turn black? The following is the beauty of the electronic ceramics manufacturers to highlight the superior performance of alumina ceramics why will turn black.

Alumina ceramic performance.

Alumina ceramics have better high temperature resistance characteristics, high mechanical strength, good conductivity. But the point to note is that when washing the ceramic, a little to use ultrasound for washing, shall not use other items for cleaning, because alumina ceramic is a very special material.

Alumina ceramics why will turn black?

Compared with other ceramic materials, alumina ceramics have very different advantages, but there is still an overall problem that plagues the majority of customers. Alumina ceramics can also turn black throughout the use of the condition, how can we solve similar problems in the face of? The blackening of alumina ceramics is one of its undeniable drawbacks, which will certainly endanger all its normal applications. It is therefore necessary to find out as soon as possible the causes of the blackening defects in alumina ceramics and glazes and to take effective measures purposefully to improve the characteristics of the goods.

The study concluded that alumina ceramics turn black simply because of the raw material and the processing. Therefore, in order to prevent the occurrence of similar defects, one needs to be careful in selecting the raw materials commonly used for enamel layers. One needs to use less or no very fume-prone raw materials, which will reduce the relative level of sensitivity of the raw material components to the atmosphere. Also, one needs to control the glaze firing temperature of alumina ceramics. In order to exceed the conditions of complete melting and brightness, one also needs to control the glaze firing temperature 12°C lower than the metallization temperature, which helps to reduce the blackening of the alumina ceramic glaze layer.
