Explanation
layered silicate mineral. It is often distorted by phlogopite. Yellowish brown, golden yellow, bronze yellow, sometimes with green. The grease or pearly luster is golden inside, and the crystal is bent like a leech worm. The density is correspondingly reduced, and it has high thermal insulation, sound insulation, insulation performance and cation exchange ability. It is formed from phlogopite and biotite by low-temperature hydrothermal alteration. It is a good heat insulation and acoustic insulation materials. It is mainly used in the construction industry. It is also used in paper making and coatings,
