1. the chemical composition of the Muscovite: KAl2[Si3AlO10] (OH, F) 2, the ideal component is eight surface body slices containing Al, but also a small amount of Fe3+, Mg, Fe 2+ even Mn, Cr, V and so on. Muscovite has high complete cleavage and pale color. The feature of the thin sheet is rich in elasticity.

4. the use and function of the Muscovite:
Muscovite has excellent dielectric properties, such as high insulation strength and high resistance, low dielectric loss, resistance to arc and corona, and is hard, high mechanical strength, high temperature and temperature change and good physical and chemical properties such as acid and alkali resistance. Therefore, it is widely used in radio industry and aviation industry. It is also widely used in coatings, paints, plastics, linoleum, paper making, oil field drilling, decorative make-up and other industries. In the paint, it can reduce the destruction of UV or other light and heat to the film, increase the acid resistance, alkali and electrical insulation properties of the coating, and improve the anti freezing, corrosion resistance, toughness and compactness of the coating. Sex, reduce the permeability of the coating, prevent spots and cracks. Mica powder can also be used in roofing materials to keep warm, heat insulation and so on. Mica powder and mineral cotton resin paint can be mixed with concrete, stone and brick walls, and mica is used for linoleum, pipe mortar and cementing agent. In rubber products, mica powder can be used as lubricating agent, film stripping agent, and high strength. Filler for electrical insulation and heat resistant, acid and alkali resistant products. Mica can also be used as mica paper, mica board, mica ceramic, Pearlescent Mica Pigment, mica casting products, etc.
