What are the uses of mica

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.

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.

Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.

What are the uses of mica

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

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?

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.

Huajing mica cosmetic grade mica powder has been loved by customers since it entered the market, and has a general response, excellent quality, stable quality and high reputation.

Natural high quality Muscovite:feel fine, soft lubrication.

For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

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.
