Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

Mica powder, known as industrial monosodium glutamate, is widely used. With the continuous development of technology and application market, and some new requirements have been put forward for the quality of mica powder, so synthetic mica powder has been developed. Compared with the natural mica powder processed by natural mica ore, and the synthetic mica powder synthesized by using a variety of raw materials through high temperature reaction and other chemical methods. What are the advantages and differences between them?

A group of parallel cleavages can be seen in a photograph of biomica under orthogonal polarized (left) and single polarized (right) mirrors.

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