Mica is a kind of rock-forming mineral,which is always presents as pseudohexagonal and rhombic platy, pieces and columnar crystal. With the changing of the chemical composition, the mica color is different. Especialy whith the increacing of the Fe, the color is darker. The characteristic of mica is insulating, heat resisting,glossy and stable physical and chemical property. It is also has better thermal insulation, elasticity and toughness.

Biotite is widely used in building materials industry, the fire extinguisher, welding wire industry, plastic industry, electric insulation industry, paper making industry, asphalt paper industry, rubber industry, pearl pigment industry, and other chemical industry.
