Die beiden bekanntesten Arten von Glimmer sind Muskovit und Biotit. Muskovit, auch als Weissglimmer bezeichnet, ist ein durchscheinender bis durchsichtiger Glimmer, der häufig in hellem Farbton vorkommt, wie zum Beispiel Grau, Gelb oder Grün. Aufgrund seiner hohen Temperaturbeständigkeit und guten elektrischen Isolationseigenschaften wird Muskovit häufig in der Elektroindustrie eingesetzt, insbesondere in Kondensatoren und Isolatoren. Zudem findet es Verwendung in kosmetischen Produkten, da es eine schimmernde Wirkung auf der Haut erzeugt.
Mica Flakes in Resin A Dazzling Combination for Art and Craft Projects
The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.
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.
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.
In conclusion, mica powder is an incredibly versatile natural resource with a multitude of applications across various industries. From enhancing cosmetics and arts to serving as a natural colorant in food and an additive in industrial processes, its unique properties make it highly sought after. As the demand for sustainable and ethically sourced materials continues to rise, the future of mica powder looks promising, provided that responsible harvesting practices are upheld. Whether you are a makeup enthusiast, an artist, or a manufacturer, mica powder offers endless possibilities for creativity and innovation.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
In response to these concerns, many brands are reassessing their supply chains. Companies are increasingly opting for mica sourced from mines that adhere to safe working conditions and fair labor practices. Consumers are encouraged to seek brands that demonstrate transparency in their sourcing processes. Labels that indicate responsible sourcing or charity initiatives in mining communities can often provide more confidence.

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.
The user experience with Mica’s eyeshadow is enhanced by the brand’s dedication to customer satisfaction. Each eyeshadow is housed in stylish, user-friendly packaging that is travel-friendly and easy to access. The soft and buttery texture of the eyeshadows allows for smooth application, while the inclusion of various finishes, from matte to satin to shimmer, gives users the ability to play with different styles. Moreover, the shadows work well with a variety of brushes and tools, making it easy to achieve desired looks.
1. Cost-Effectiveness Purchasing mica powder in bulk significantly reduces the cost per unit. For startups, this is essential in maintaining a reasonable budget while ensuring high-quality ingredients in their formulations.
- Combining Colors Don’t be afraid to mix different mica colors together! Layering or swirling different shades can lead to unique and eye-catching results.
In product categories, mica’s versatility spans various functionalities. Cosmetic-grade mica, for instance, is valued for its shimmering properties, making it a staple in beauty products such as eyeshadows and highlighters. Suppliers specializing in cosmetic mica often highlight their compliance with safety regulations and chemical testing results to reassure clients of the product's safety for skin application.
