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.

What are the uses of mica

Natural high quality Muscovite:feel fine, soft lubrication.

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

Despite the benefits, the use of mica powder in cosmetics has not been without controversy. One significant concern involves the sourcing of mica. A large portion of the world’s mica supply comes from regions with poor labor practices, including child labor and unsafe working conditions. As consumers become more aware of ethical sourcing, many companies are taking steps to ensure their mica is sourced responsibly, opting for synthetic alternatives or purchasing from suppliers that adhere to fair labor practices.
