Structure and chemical composition of sericite mica
The Sericite mica is one kind of natural fine grain muscovite mica, is subspecies of muscovite, is the laminated structure silicate, the structure clamps an alumina octahedron constitution duplicate silica level by two silicas tetrahedrons (to see chart one). {001} cleaves completely, may deduct the extremely thin laminated shape, the piece thick may reach below 1u (theoretically to be possible to hew 0.001u), the big ratio of diameter to thickness. Compares with muscovite mica: has the natural particle size small, is easy to process the superfine characteristic. The sericite mica crystal chemical formula is: K0.5-1(Al, Fe, Mg)2(SiAl)4O10(OH)2�nH2O, , General chemical composition: SiO2 43.13~49.04%� Al2O3 27.93~37.44%� K2O+Na2O 9~11%�H2O 4.13~6.12%�
