MICA is a layered silicate structure composed of two layers of Silicon-oxygen tetrahedron with a layer of aluminum oxide octahedral compound consisting of Silicon-oxygen layer. Cleavage complete, can be split into very thin sheets, sheet thicknessup to 1 μ m (theoretically shaved 0.001 μ m), large diameter-thickness ratio; MICACrystal chemical formula: K0.5-1 (Al,Fe,Mg) 2 (SiAl) 4O10 (OH) 2  nH2O, General components: SiO2:43.13-49.04%, Al2O3:27.93-37.44%,K2O+Na2O:9-11%,H2O:4.13-6.12%.
