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.

Mica is a silicate mineral composed of multiple layers of silicate sheets that can be separated into thin, flexible sheets. This property, along with excellent thermal resistance, electrical insulation capabilities, and resistance to moisture, makes mica particularly valuable. It is widely used in products such as makeup, insulation materials for electrical devices, and as a filler in various applications.

Mica powder's versatility allows it to be utilized across a multitude of cosmetic products. In powder form, it can be easily blended into foundations, mineral makeup, blushes, and eyeshadows. Its fine particle size ensures a smooth application, creating a second-skin effect that enhances wearability and comfort. Furthermore, mica is also hydrophobic, meaning it repels water, which can help improve the longevity and performance of makeup products, making it ideal for long-lasting formulations.

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.
