Phlogopite has high dielectric strength and greater resistance, low dielectric loss and anti-arc, resistance to corona and other excellent dielectric properties, and the hard texture, high mechanical strength, high temperature and rapid temperature changes and with acid base, good physical and chemical properties, therefore, widely used in the radio industry, aviation industry, motor manufacturing, it is widely used in coatings, paints, plastics, linoleum, paper, oil drilling, decorative cosmetics and other industries, can be reduced in the paint ultraviolet light and heat or other damage to the paint film to increase the coating acid, alkali and electrical insulation, coatings to improve the frost resistance, corrosion resistance, toughness and density, lower permeability of the coating to prevent spots and cracks. Gold mica powder can also be used in roofing materials, rain from the warm, heat insulation, gold mica powder mixed with mineral wool resin coating, do concrete, stone, brick exterior decorative effect, mica pieces for linoleum, mortar tube, cementing agent; in rubber, gold mica do lubricants, mold release agent, and to do high-intensity electrical insulation and heat, acid and alkali products, fillers.
