Par ailleurs, la poudre de mica est souvent utilisée dans la fabrication de savons faits maison. Elle permet d'obtenir des couleurs vives et attrayantes, tout en ajoutant une touche de brillance. Les artisans apprécient également sa capacité à se mélanger facilement avec d'autres matériaux, ce qui offre une grande flexibilité créative.

Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.

Given the environmental and ethical issues surrounding mica extraction, there is a growing movement towards sustainable practices in the mica industry. Organizations and advocacy groups are working to promote responsible sourcing and improve the living conditions of mining communities. Initiatives focus on establishing supply chain transparency, ensuring that companies can trace their mica back to its source, thereby reducing the risk of child labor and exploitation.

Mica is a naturally occurring mineral that has been valued for its unique properties and aesthetic appeal in various industries. Among its many applications, mica has found a significant role in the automotive paint industry. This article explores the reasons behind its popularity, its benefits, and the advancements in automotive coatings using mica.
