Description:
Mica is a rock-forming mineral with a hexagonal flaky crystal shape and is one of the main rock-forming minerals. The mica crystal has a layered structure inside, so it is a sheet crystal, mainly hexagonal sheet crystal. The characteristic is insulation, high temperature resistance, and the most used industrially is sericite, which is widely used in coatings, paints, electrical insulation and other industries.
