Moreover, the mica industry has been marred by ethical concerns, particularly concerning child labor. Mica is often mined in developing countries where labor laws may be inadequately enforced. Reports of children working in dangerous conditions to extract mica for very low wages have raised significant concerns among consumers and advocacy groups. Companies must ensure that their supply chains are free from child labor and exploitation, promoting ethical sourcing practices that respect workers' rights.

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.

4. Sealants and Adhesives Mica powder improves the performance of sealants and adhesives by enhancing their flexibility and resistance to temperature fluctuations. This is essential for ensuring the longevity of joints and seals in automobiles.

The mica process is a multifaceted journey that highlights the mineral's indispensable role in modern industries while underscoring the pressing need for ethical sourcing and sustainable practices. As the demand for mica continues to grow, so does the responsibility of industries and consumers alike to ensure that this valuable resource is obtained in a manner that respects both people and the planet. By supporting sustainable initiatives and seeking transparency in the mica supply chain, we can contribute to a future where the benefits of mica are enjoyed without compromising ethical standards or environmental health.
