Mica is sweet, mild, and has no sense of muscle like a dead person. Be injured by wind evil and cold, fever, as the body sitting on the ship, dizzy, with masonry except wind evil, and enrich the five zang organs, increase fertility, make the eyes bright, long wearing the body light, smart and prolong life. Also known as clouds, clouds, clouds, clouds, clouds, clouds, clouds, sand, phosphorus and stone, produced in the depths of the mountains.
Biotite industry mainly uses the insulation and its heat resistance, acid and alkali resistance, and compressive strength and exfoliation of insulating material is used as electrical equipment and electrical equipment; secondly for furnace window and machinery manufacturing steam boiler, smelting furnace of the parts. Mica and mica powder can be processed into mica paper, and can also be used instead of mica sheet to produce insulating materials with low cost and even thickness. The main use in industry is the muscovite, and the second is gold mica. It is widely used in building material industry, fire fighting industry, fire extinguishing agent, electric welding rod, plastic, electric insulation, paper making, asphalt paper, rubber, pearlescent pigment and other chemical industry. Superfine mica powder can be used as functional fillers such as plastics, coatings, paints and rubber to improve its mechanical strength, toughness, adhesion, aging resistance and corrosion resistance. In addition, corrosion, elasticity, toughness and sliding resistance and noise, low coefficient of thermal expansion properties such as high electrical insulation, and launched the first two characteristics of sheet surface smooth, diameter thickness ratio, regular shape, strong adhesion.
Mica is a general term for mica group minerals. They are potassium, aluminum, magnesium, iron, lithium and other metal silicate. They are layered structures and monoclinic systems. The crystals are false, six - side, flaky or plate-like, sometimes columnar. The layered cleavage is very complete and has a glassy luster, and the flakes are elastic. The refractive index of mica increases with the increase of iron content, and can rise from low positive to middle protuberance. An iron free variety; colorless in flakes; the more iron, the deeper the color; and the increased colour and absorbency.
