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.

The incorporation of non-metallic mica powder into various products offers several benefits
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.

The popularity of mica powder in cosmetics is undeniable, with its rise coinciding with the growth of the natural beauty movement. As consumers become more educated about the ingredients in their products, they seek formulations that contain natural minerals. Mica powder fits this demand, serving as a bridge between beauty and nature.
Mica’s shimmering effect can be attributed to several factors, including its light-reflective properties and the way its thin flakes interact with light. When light strikes a gold mica pigment, it is reflected off the smooth surface of the individual mica particles. This reflection is further enhanced by the mineral’s unique plate-like structure, which scatters light in different directions, creating a soft, glowing effect.
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.
As consumers become more eco-conscious, the demand for sustainable and non-toxic pigment options has risen. Many manufacturers are responding by creating pearl pigments derived from natural sources, ensuring that they are safe for both the environment and the end-user. These sustainable alternatives contribute to a greener supply chain while still delivering the same captivating effects.
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?

3. Plastics and Coatings The versatility of natural mica-based pigments extends to plastics and coatings as well. These pigments can be used in various formulations to improve aesthetic qualities, providing a shiny or matte finish depending on the application. Their heat resistance also makes them suitable for high-temperature applications, ensuring that the vivid colors remain stable even under extreme conditions.
