With a silky luster appearance, sericite is a natural fine-grained muscovite with the characteristics of small natural particle size and easy processing and ultra-fineness. The chemical formula of sericite crystal is: K0.5-1 (Al,Fe,Mg)2(SiAl)4O10 (OH) 2·nH2O, a compound silicon-oxygen layer composed of two silicon-oxygen tetrahedrons and a layer of aluminum-oxygen octahedron , which can be split into very thin flakes, with large radius-thickness ratio, flexible and bendable. At the same time, it has outstanding characteristics such as acid resistance, alkali resistance, salt spray resistance, high temperature resistance (above 600 ℃), electrical insulation, and good wear resistance. In addition, the chemical composition, structure, and structure of sericite are similar to that of kaolin, and it also has certain characteristics of clay minerals, that is, it has good dispersion and suspension in water media and organic solvents. Therefore, sericite has characteristics of both mica minerals and clay minerals.
