Muscovite ( Figure 2 ) Muscovite is characteristic of insulation, high temperature, shiny, stable physical and chemical properties, has good heat resistance, flexibility and toughness. Processed into mica powder has good sliding and strong adhesion. As a result of mica and mica powder itself performance, mainly has the following purposes: daily chemical raw materials, ceramic raw materials, mica paint additive, plastic and rubber filler, construction materials, used for coating protective layer, used for drilling mud additive, in recent years in the glass flake replacement is also very prominent.

Muscovite, belonging to the silicate category, chemical formula: KAl2 ( AlSi3010 ) ( OH ) 2, monoclinic, hardness 2.54 2.772.88, proportion, in natural environment often takes a plate shape fake six surface shaped crystals, flaky or scaly. Color from colorless to white, sometimes with a green, brown, is a colorless, with glass or pearl luster. Have development very good basal cleavage, often can be a piece of torn mica.

Distribution range
