muscovite

Mica：potassium, aluminium, magnesium, iron, lithium, etc the floorboard of the layered structure of aluminum silicate.mica mineral in one of the most common minerals are kind of biotite, Muscovite and phlogopite mica, lithium, sericite, etc

Muscovite and phlogopite has good electrical insulation and thermal conductivity, acid resistance, alkali resistance and pressure resistance, and thus is widely used to make electrical and electronic industrial insulation. Mica pieces and used as a filler powder, etc. Lithium mica is the main mineral raw materials for extraction of lithium.
