Muscovite

Muscovite Description:

Muscovite mica is also called ordinary, potassium mica or mica is a mica mineral. Muscovite is a good electrical insulator and thermal insulator, and it can be mass produced, it has important economic value. It is produced in the metamorphic rocks in general, but also produced in the granite rocks. Muscovite is not just white, it can be a lighter brown, green, red to colorless, with vitreous luster to the silk shine. Large plate-like shape, the six-party collection of crystal or fine.

Muscovite is very broad divided one of rock-forming minerals in the rocks in both the three outputs. Pelites during regional metamorphism in the lower to the formation of sericite, while slightly higher metamorphic grade, as muscovite. Magmatic crystallization of the role of late and pegmatite stage, have generated a lot of muscovite. From high to low temperature alteration in the process, but also can generate. The so-called greisen alteration of one of the high temperature, can form a large number of muscovite. The role of the so-called low temperature sericite alteration, one can form a large number of sericite. Weathered muscovite broken into very fine scales, both clastic sediments can become debris, it can be one of the mineral composition of mudstone. Muscovite schist occurred mainly in the acidic magmatic rocks; In addition, they are often found in greisen, metamorphic schist and gneiss. Muscovite granite in the middle, often forming large crystals of industrial value; muscovite pegmatite formation of multi-stage; hydrothermal metal deposits and hydrothermal metamorphic rocks, sericite role in China is widespread, forming sericite; muscovite in the metamorphic rocks is widely distributed, it is clay and rock in the higher temperature under the action of potassium in the formation.

The main purpose of muscovite Description:

Most used in industry is muscovite, which are widely used in building materials industry, the fire industry, fire extinguishing agents, welding, plastics, electrical insulation, paper, asphalt paper, rubber, pearlescent pigments and other chemical industries. Ultra-fine mica powder for plastics, coatings, paints, rubber and other functional fillers can increase the mechanical strength, enhanced toughness, adhesion and anti-aging and anti-corrosion type. In addition to very high electrical insulation, anti-acid corrosion, flexibility, toughness, and sliding resistance, heat insulation, thermal expansion coefficient and other properties, but also the first to introduce chip and Two smooth surface, radius to thickness ratio, regular, with with strong characteristics.
