Precautions for improving the toughness of brown corundum

For brown corundum, the key is to have good toughness, which is also an important basis for us to select brown corundum products. But in fact, the toughness of brown corundum is directly related to many factors. In order to ensure this performance, what should we pay attention to?
After in-depth research, it is found that the toughness of brown corundum is mainly affected by the following factors. For example, the content of silica in brown corundum is too much to be retained. On the contrary, it will react with alumina, thus reducing the toughness of brown corundum products. Secondly, it is possible that the sulfur content in brown corundum is less than the standard value, which will also have a negative impact on its toughness.
For this reason, we need to pay attention to the aluminum content in brown corundum, because generally, the higher the aluminum content, the better the toughness of the product. In addition, we should also pay attention to the calcination process of brown corundum, which must be carried out strictly according to the requirements, so as to produce products that meet the requirements.
