Understanding Pearlescent Pigments

Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.

Controversies and Concerns

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.

Moreover, there is a concern about the entire life cycle of synthetic mica products. For instance, while the raw materials used in synthetic mica are often sourced in a more sustainable manner, the environmental impact of those raw materials must also be accounted for. Comprehensive assessments that take into consideration sourcing, manufacturing, packaging, and disposal are essential to determine the true environmental impact of synthetic mica compared to natural mica.

What are the uses of mica

From a professional standpoint, expertise in the Chinese mica market highlights the significance of partnerships between research institutions and manufacturing hubs. Such collaborations facilitate the development of novel applications and the improvement of existing products. For instance, the synergy between scientists specializing in mineralogy and engineers in the electronics field has led to advancements in mica capacitors and insulators, driving efficiencies in energy consumption and thermal management in electronics.

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 naturally occurring mineral that is composed of crystalline silicate. It is known for its unique properties, which enable it to be finely milled into a powdery form. This powder is primarily used in cosmetics due to its ability to reflect light, which gives products a luminous quality. Mica is commonly mined from various regions around the world and comes in numerous colors and textures, making it an incredibly versatile ingredient.
