3. Phlogopite Mica

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.

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.  

3. Texture and Dimension When mica powder is added to paint, it not only contributes color but also texture. The graininess of the powder can create a tactile surface that enhances the visual appeal of the final piece. Artists can experiment with different amounts of powder to achieve the desired level of shimmer and texture.

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.

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 awareness of environmental issues continues to grow, the demand for sustainably sourced ingredients in cosmetics has become paramount. All-natural mica powder can be sourced responsibly, with many suppliers committed to ethical mining practices that protect both the environment and the communities involved in extraction. By choosing all-natural mica powder from reputable sources, consumers can support sustainable practices and contribute to a more ethical beauty industry.

Furthermore, the incorporation of mica into automotive paints can improve their thermal stability. Mica's natural heat resistance helps prevent the paint from fading or degrading over time, enhancing the longevity of the vehicle's exterior. This thermal stability is critical in protecting the vehicle's underlying materials, as prolonged exposure to high temperatures can lead to paint failure or damage to the substrate these coatings protect.

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.
