Mica:
Mica main crystallization monoclinic crystal was thin at the six-party Flake, Flake, tabular and sometimes six-party column was false. Hardness 2 -3, the proportion of 2.70-3.20. Mica of refractive index increased iron content and the corresponding increase was protruding from low to CKS processes. Non-ferrous variant SHEET colorless, higher iron content, the greater the color and multi-color and enhance the absorbability.
Mica varieties:
Muscovite | Biotite | Phlogopite | Sericite | Green Mica |
Mica Model :Mica ore, mica films, the main specifications are Muscovite :8-10 head ,10-20 head ,20-40 head ,40-60 head,60 -100 head projects, 100 projects, 200, and 325 etc.
Physical Characteristics:Mica is a type of water layered silicate minerals, many types, the Muscovite has a unique acid and alkali resistance, chemical stability, also has good insulation and heat resistance, is not combustible, corrosion protection.
Mica chemical composition :
Ingredients | SiO2 | MgO | Al2O3 | Cao | Fe2O3 | K2O | Na2O | Loss on Ignition |
Content% | 44.3 | 0.62 | 31.21 | 0.75 | 5.74 | 10.58 | 1.17 | 4.97 |
Mica use :The industrial use was most of the Muscovite, followed by the mica. Its widely used building materials industries, fire industry, fire-extinguishing agent, welding electrodes, plastic, wire insulation, paper and paper asphalt, rubber, Pearlescent pigments and other chemical industries. Ultra-fine mica powder for plastics, coatings, paints, rubber and other functional fillers can increase its mechanical strength, increase toughness, Adhesion anti-aging and corrosion resistant type. In addition to the very high electric insulation, acid-base corrosion resistance, flexibility, toughness and sliding, heat noise, thermal expansion coefficient of small properties, the first to launch two unit-smooth surface, the radius to thickness ratio, morphology, adhesion characteristics. Major industrial use its insulation and heat resistance, and acid-fast, alkali resistance, resistance and sexual exploitation. for electrical equipment and electrical equipment insulation material; Secondly used in the manufacture of steam boilers, smelting furnaces and windows and mechanical parts. Mica broken and can be processed into Muscovite mica paper, can also perform various Mica unit low-cost manufacturing, uniform thickness of insulation material.
