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.

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

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.

One of the key advantages of pearlescent pigments is their versatility. You can find them in a wide range of cosmetic items, including foundations, blushes, eyeshadows, highlighters, and lip products. For instance, in eyeshadows, pearlescent pigments can create captivating looks that enhance the eyes, making them pop with vibrancy. Similarly, highlighters infused with these pigments can give the skin a radiant glow, enhancing cheekbones and creating a youthful appearance.

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 powder has gained considerable popularity in recent years, particularly in the fields of cosmetics, arts and crafts, and even home decor. This versatile mineral, often celebrated for its shimmering, reflective properties, is a must-have ingredient for anyone looking to add a touch of glamour to their creations. In this article, we will explore what mica powder is, its natural origins, its applications, and why choosing natural mica powder is essential for both health and environmental reasons.

The unique properties of fluorophlogopite make it valuable in various industries. Due to its high thermal stability and electrical insulation properties, it is extensively used in the production of capacitors, dielectric insulators, and in applications requiring reliable heat resistance. In the cosmetic industry, its natural shimmer and reflective capabilities make it a popular ingredient in products like eyeshadows and highlighters. Additionally, its layered structure allows it to be used in paints and coatings, providing a lustrous finish.

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.  

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

Muscovite forms under metamorphic conditions, where rocks are subjected to high temperatures and pressures. These conditions alter the original minerals, leading to the recrystallization of new minerals, including muscovite. It is commonly found in metamorphic rocks such as schists and gneisses, as well as in igneous rocks that have undergone alteration.
