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.
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.
In 2022, Lingshou Huajing Mica Co., Ltd. launched cosmetic grade mica powder. The flake structure of mica powder can lock the water on the surface of the skin, forming a protective film to effectively prevent water loss. Its unique gloss and reflection effect add natural and charming luster to the skin, and mica powder also has a certain sunscreen effect. To a certain extent, it can reduce the damage of ultraviolet rays on the skin, protect the skin from the external environment, and prevent sunburn.
In addition, lepidolite and ferrolepidolite can also be used as mineral raw materials for extracting lithium.

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.
The mining and processing of mica have historically raised concerns about ethical practices and sustainability. However, many companies are now sourcing all-natural mica powder from responsible suppliers who prioritize ethical mining practices. This shift ensures that the products not only meet consumer demand for quality but also adhere to fair labor standards and environmental regulations. By supporting brands that are committed to sustainability, consumers can enjoy the benefits of mica powder while contributing to more responsible industry practices.
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.
In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.
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.

While the advantages of external wall insulation paint are clear, it is essential to consider a few factors before making a decision. The effectiveness of the insulation paint can vary based on the type of surface, the climate in which one lives, and the specific product used. It’s advisable to conduct thorough research and possibly consult an expert to determine the best option for your particular structure and needs.
