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.

The mica powder of HUAJING has the advantage of extremely narrow particle size, and the particle size specifications are complete, such as: 2000 mesh, 1250 mesh, 800 mesh, 400 mesh, 120 mesh, etc. The skin feeling is exquisite.

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.

Layer upon layer of mica

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.

What are the uses of mica

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

In recent years, the mineral mica has garnered significant attention in China, as well as globally. Mica, a naturally occurring mineral, is renowned for its unique properties, including its ability to withstand high temperatures, its electrical insulating properties, and its shimmering aesthetic appeal. These characteristics have made mica an essential ingredient in various industries, including cosmetics, electronics, automotive, and construction. With China being one of the largest producers and consumers of mica, understanding its role in the Chinese market is crucial.

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.
