The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.
A group of parallel cleavages can be seen in a photograph of biomica under orthogonal polarized (left) and single polarized (right) mirrors.
The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

The popularity of unconventional colors—such as neon shades and deep jewel tones—also plays into the modern makeup trend of self-expression. In a world where individuality is highly celebrated, these vibrant pigments allow users to step outside of traditional beauty norms and explore their creative sides.

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?
Renowned manufacturers have invested heavily in research and development to innovate within the realm of mica processing. Cutting-edge technology and a deep understanding of the mineral’s characteristics allow them to offer an array of products that cater to specific industry needs. For instance, in the electronics industry, mica is utilized for its superior dielectric strength and thermal stability. Manufacturers produce ultra-thin mica sheets that serve as insulators in high-voltage equipment and as substrates in circuit boards, ensuring efficiency and durability.
One of the most prevalent uses of mica powder is in the cosmetics industry. Mica is commonly used as a natural pigment in makeup products such as eyeshadows, blushes, and highlighters. Its ability to reflect light gives cosmetics a vibrant sheen and a beautiful finish, enhancing the overall aesthetic appeal. Mica powder is favored not only for its vibrant colors but also for being a natural mineral, making it a popular choice among consumers seeking eco-friendly and non-toxic beauty products. Additionally, mica is also used in various skincare products due to its ability to provide a smooth and even application, giving a polished look without heavy coverage.
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.
Industrial Applications
The mica industry is undergoing profound changes. With the help of emerging industries, the mica industry will be a large market of more than 10 billion.
