The layered structure of mica makes it strippable to some extent, so it is widely used as fireproof, heat-insulating and insulating materials in the field of building materials. In the field of electronic materials, mica is used as insulating material for capacitors, electric heaters and other components. In addition, mica is one of the important rock components, which is of great significance in geological research. Generally speaking, mica is a very important mineral, and its wide application fields and important geological significance make it an important object of mineralogical research.
