Alumina ceramic sheets are also known as wear-resistant alumina ceramic linings, high-alumina linings, wear-resistant ceramic linings, alumina ceramic patches. Alumina ceramic sheets are mainly made of al2o3 as raw materials and rare metal oxides as solvents. It is calcined at a high temperature of 1700 ° C. So how do we identify alumina ceramic sheets? First of all, we have to look at the surface of the alumina ceramic sheet. The surface of a good alumina ceramic sheet is very smooth, without black spots on the surface, and the color is uniform. Secondly, we can identify the alumina ceramic sheet by measuring the density. Knowing the content of alumina, there Read more
