The unique properties of flogopita have led to its utilization in a wide range of applications

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.

Additionally, the lack of effective monitoring systems makes it difficult to verify the source of mica once it enters the supply chain. Mica is often processed, blended, and sold through multiple intermediaries before reaching cosmetic manufacturers. This fragmentation of the supply chain makes it even harder to track and audit the conditions under which the mica is mined.

Mica is a group of silicate minerals known for their sheet-like crystalline structure. When ground into a fine powder, it exhibits a variety of characteristics that make it appealing for numerous applications. The natural luster of mica powder allows plastic products to maintain aesthetic appeal, providing a sparkling or shimmery finish that many consumers find attractive. Furthermore, mica powder is safe and non-toxic, which aligns with the growing trend of eco-friendly materials in the manufacturing sector.
