Whiteness is one of the main parameters of kaolin\'s technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and whiteness after calcination. For ceramic raw materials, the whiteness of calcined is more important, the higher the whiteness of calcined, the better the quality.
Ceramics, rubber,
plastics, artificial leather, cement, refractory materials,
chemical industry and agriculture are not widely used
