Analysis on the hardness of high temperature alumina

Although the activity of high temperature alumina is more critical under high temperature environment, the hardness of the high temperature alumina needs to be considered in the process of use. Below, we will analyze the hardness of the high temperature alumina.
1. The real hardness of high-temperature alumina is related to the material. For example, the hardness of alumina is about 9 on the Mohs scale. Although various aluminas are similar, the hardness of different alumina bodies is different. This is because of high-temperature oxidation. Aluminum is usually an agglomerate. The attached picture is an electron micrograph of a polishing powder agglomerate.
2. Because the firing temperature is different, the strength of the agglomerates is also different, so when using, there will be a different feeling of hardness. Of course, some hardening materials such as alumina are added to some polishing powders, and the grinding rate and wear resistance will be improved.
In short, the hardness of high-temperature alumina is mainly related to the material and temperature. Therefore, when producing, pay attention to its material and temperature to improve the quality and hardness of high-temperature alumina.
