Kaolin

Kaolin is a natural clay mineral primarily composed of kaolinite. Due to its exceptional whiteness, plasticity, chemical stability, and adsorption properties, it is widely used in ceramics, paper, coatings, rubber, and chemical industries. Based on processing methods, kaolin is categorized into hydrous kaolin and calcined kaolin. Hydrous kaolin, with a whiteness ≥85%, is used in ceramics and coatings. Calcined kaolin, with a whiteness ≥92% and increased oil absorption, is applied in paper and rubber industries.
