Mica is the common name of mica group minerals. It is the aluminosilicate of potassium, aluminum, magnesium, iron, lithium and other metals, it's in layer structure and in monoclinic crystal state.
Mica ore mainly includes biotite, phlogopite, muscovite, lepidolite, sericite, chloritite, ferro-lepidolite and so on, and aventurine is a mixed mineral of mica and quartz. The most used mica products in industry are muscovite and phlogopite. Lepidolite is an important mineral material for lithium extraction.
[Nature and characteristics]
Mica's feature is it can be peeled and cut.
Mica is a good electrical and thermal insulator, and it can be mass produced, so it has important economic value.
