super grade mica powder

super grade mica powder Mica powder is a group of aluminum silicate minerals with layer-structure, and rich in elements of potassium(K), aluminum(Al), magnesium and lithium etc. Dolomite (White Mica) is one of the similar sub-categories in mica group. It is transparent with no color or light color, and possesses the glasss shine. Its Mohs hardness is about 2-2.5, specific density is 2.7-3.5. Dolomite possesses lots of excellent properties, for example electric insulating, high temperature proof, acid and alkali resist, and corrosion proof ect.Element Data for Reference:ElementSiO2Al2O3K2OFe2O3CaONa2OMgOH2OContent%44 5020 339 112 60.02 0.770.6 1.80.3-22-3Specifications and Data for Reference: 1.
