Understanding Mica

สรุป

Natural mica flakes have captivated the attention of craftsmen, artists, and manufacturers for centuries. Revered for their shimmering beauty and versatility, these mineral-based particles possess unique properties that make them ideal for a wide array of applications, from cosmetics and art to construction and electronics. In this article, we will delve into the characteristics, uses, and advantages of natural mica flakes, exploring why they are a sought-after material in various industries.

Conclusion

The demand for golden mica is primarily driven by its applications in cosmetics and construction materials. In cosmetics, manufacturers utilize mica to add a glimmering effect to products such as eyeshadows, highlighters, and lip glosses. The beauty industry's continuous growth globally has significantly boosted the demand for high-quality, aesthetically pleasing mica, particularly the golden variety.

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.
