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.

The allure of mica is largely attributed to its unique physical and chemical properties. Known for its insulating capabilities, flexibility, and resistance to heat, mica is an ideal component in the manufacturing of electronic devices. In an era where technological innovation is at the forefront, mica factories have become central to the production of efficient and durable electronic components such as capacitors, semiconductors, and insulators. By prioritizing precision and quality in the processing of mica, these factories cater to the stringent demands of the electronics industry, thereby establishing a reputation for reliability and expertise.

China's role in the global mica market is amplified through strategic export channels and a robust distribution network, ensuring that industries worldwide have access to this vital resource. The country's commitment to expanding its reach in existing and emerging markets is evident through consistent reinvestment in technology and employee skill development.

To address these issues, some companies have switched to using synthetic mica, which is produced in a controlled, ethical environment. Others support initiatives that ensure the proper treatment of workers and the environment in mica-producing regions. As the beauty industry moves toward more sustainable and ethical practices, sourcing mica responsibly has become a key consideration for many brands.
