Calcined kaolin

Kaolin is a mixture of inorganic and non-metallic materials. Calcination of kaolin is to sinter kaolin into a certain temperature and time in a calciner so as to change its physical and chemical properties to meet certain requirements. The whiteness is one of the main parameters of the technological properties of kaolin, and the high purity kaolin is white. The whiteness of kaolin can be divided into natural whiteness and calcined whiteness. For ceramic raw materials, the whiteness after calcination is more important, and the higher the whiteness, the better the quality.

Usage: It is not widely used in ceramics, rubber, plastics, artificial leather, self-cement, refractory, chemical industry and agriculture.
