(1) Used in decorating, paint and coating.
(2) Mica powder is the basic raw material for mica ceramics products.
(3) It can be used in fire-fighting dry powder, protecting layer of welding rods, conducting wires and electric cables.
(4)It can be taken as a filler, shelter, lubricating substance, drawing of patterns in plastics, rubber, asbestos products and sealing materials. It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products. It can be used as coating in models of forcasting metal, the brightening material in aluminium and paint in electroplating bath.
