Mica is a new non-metallic crystal material, a national key new material, with heat insulation, insulation, high temperature resistance characteristics, is an important material in aerospace, rail transit, nuclear power, wind power, aircraft carriers and other high-tech fields, but also electrical equipment, wire and cable, household appliances indispensable insulation material, in the national economy and national defense construction plays an important role.

Mica powder is derived from mica, a naturally occurring silicate mineral that is ground into fine particles for use in cosmetics. Unlike synthetic ingredients that may contain artificial dyes or fragrances, mica powder for skin for cosmetics is generally free from toxic chemicals, making it a safer option for sensitive skin. Its hypoallergenic nature means that it is less likely to cause irritation or allergic reactions, which is crucial for people with conditions like rosacea, eczema, or dermatitis. When applied topically, mica powder creates a light-reflective surface without overwhelming the skin with harmful additives.

X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

In addition, lepidolite and ferrolepidolite can also be used as mineral raw materials for extracting lithium.
