The difference between alumina ceramics and ordinary ceramics？
Ordinary ceramics are made of clay as the main raw material and other natural minerals through crushing, kneading, molding and calcination. It is a traditional porcelain as a handicraft.
Alumina ceramics are special corundum ceramics made of Al2O3 as the main raw material, rare metal oxides as flux, and fired at a high temperature of 1650 degrees, also known as precision ceramics and special ceramics. Compared with ordinary ceramics, the manufacturing process is also very different. There are many molding methods for alumina ceramics, such as dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. way. With high hardness, it has the characteristics of wear resistance, high temperature resistance, corrosion resistance and impact resistance. It is a high wear-resistant material and is used for equipment wear resistance in various industries such as steel, cement, coal, and chemical industry.
