Sericite is a kind of flake fine-grained mica with silk luster. Due to its small grain diameter, it’s easy to apply ultra fine grain treatment. Sericite has multi-layered structure of aluminum silicate sheets, consisting of two layers of silica oxygen tetrahedron and one layer of aluminum oxygen octahedron「K0.5-1(Al,Fe,Mg)2(SiAl)4O10(OH)2·nH2O 」. Mica can be peeled into razor-thin flexible flake and it has large radius-thickness ratio and high resilience. Meanwhile the obvious features of mica are resisting to acid, alkali, high temperature「above 600℃」, abrasiveness and insulating electricity. In addition, the chemical composition and structure of sericite are similar to Kaolin, it can be dispersed or suspended in an aqueous medium. And therefore, sericite has both mica minerals and clay minerals’ characteristics.
