Application of calcined kaolin

Calcined kaolin is different depending on the application industry. Different calcination processes are applied to kaolinite. One is high temperature calcination to increase whiteness. The kaolinite and dyed minerals undergo a mineral phase transition at high temperatures, and the whiteness is greatly increased. Adapt to the requirements of the coating industry. Second, medium-temperature calcination converts kaolinite into metakaolin and silica-alumina spinel at medium temperature, increasing the chemical activity of calcined kaolin, producing the ability to adsorb and control the ions, improving the electrical insulation properties of the material, and also for wire and cable. The industry specializes in production. High-temperature calcined kaolin has high whiteness and is mainly composed of high-temperature minerals. The hardness increases, the activity decreases, and the insulation performance deteriorates.
