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.

The aesthetic properties of eco-friendly mica powder deserve special mention. This pigment comes in a wide array of colors and finishes, from matte to iridescent. Its fine texture blends seamlessly into products, imparting a luxurious glow while remaining gentle on the skin. Companies that prioritize eco-friendly ingredients often combine mica powder with other natural elements, ensuring that their products are not only visually appealing but also safe for the environment and the user.

Mica is a naturally occurring mineral that is prized in the beauty industry for its unique ability to provide shimmer and luminosity to products. Traditionally, mica has been sourced from mines, particularly in countries such as India and Madagascar. However, the mining process often involves severe labor abuses, including child labor and unsafe working conditions. Furthermore, mica mining contributes to environmental damage, including deforestation and ecosystem disruption.
