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.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.

The Allure of Cosmetic Mica Powder A Shimmering Revolution in Beauty Products
يتكون مسحوق الميكا من صفائح رقيقة من المعادن التي تمتاز بالشفافية واللمعان. يمكن العثور على مسحوق الميكا بألوان متعددة، مما يجعله خياراً مثالياً لإضافة لمسات لونية إلى الصابون. بالإضافة إلى ذلك، فإن الميكا آمنة للاستخدام على البشرة، مما يجعلها مناسبة لتطبيقها في مستحضرات مثل الصابون.
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.

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.

Mica, a naturally occurring mineral widely recognized for its versatile applications, has been at the forefront of innovation in industrial and technological contexts for decades. In China, mica has carved a niche for itself, becoming an indispensable component across various product categories. This mineral, characterized by its unique sheet-like structure, exceptional thermal resistance, and electrical insulation properties, has become synonymous with quality and reliability.
Mica is a group of silicate minerals known for their exceptional layering properties. Comprising mainly muscovite and phlogopite, mica can be split into thin, flexible sheets. These sheets can then be ground into fine or coarse flakes, depending on the required application. Mica is non-toxic and chemically inert, making it an attractive option for several sectors, including beauty, automotive, construction, and electronics.
Lepidolite is a lithium-rich mica and is notable for its lavender or pink coloration, owing to the presence of lithium-rich minerals. This rare form of mica is primarily used as a source of lithium, which is a critical component in batteries, particularly lithium-ion batteries for electric vehicles and portable electronics. Lepidolite’s unique beauty also makes it popular among collectors and in ornamental applications.

3. Lip Products Many lipsticks and lip glosses also include mica powder to provide a glossy finish and enhance color payoff. The shimmering effect not only makes the lips appear fuller but also adds an attractive dimension to the overall lip look.
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?
Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.
Moreover, mica powder is making waves in the home decor industry. It is increasingly being used in paints, wallpapers, and textiles to create stunning visual effects. The use of mica in interior design adds a touch of elegance and sophistication, transforming ordinary items into extraordinary pieces. Its reflective properties can enhance natural light in a space, thus creating an inviting ambiance.
Despite the benefits and popularity of mica, the sourcing of this mineral has raised significant ethical concerns. Much of the world's mica supply comes from regions in India and Madagascar, where mining practices are often unregulated. This can lead to serious human rights issues, including child labor and unsafe working conditions.
The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.
