Understanding Mica-Based Pigments

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.

L'une des utilisations les plus connues de la poudre de mica est dans l'industrie cosmétique. Utilisée dans des produits tels que les fards à paupières, les blushs, et les poudres illuminatrices, elle permet d'obtenir un éclat subtil et naturel. Le mica est également apprécié pour sa capacité à absorber l'excès d'huile, ce qui le rend idéal pour les peaux grasses.

- 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.

Mica powder has emerged as a popular additive in the world of epoxy resin projects, bringing a vibrant and shimmering quality to a variety of creations. Whether you are an artist, a hobbyist, or a professional, understanding how to use mica powder in your epoxy works can yield stunning results that are both visually striking and highly durable. This article will guide you through the benefits, application techniques, and considerations when using mica powder for your epoxy endeavors.

- Painting Painters can use mica powder to create vibrant, shimmery paints. By mixing the powder with acrylic medium or watercolors, artists can achieve a unique texture and luminosity in their artwork. It's perfect for adding highlights to paintings or for creating mixed media pieces.

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.
