Mica refers to a group of minerals that have perfect cleavage, allowing them to be split into thin, flexible sheets. These minerals can be found in a variety of forms, including muscovite (white mica) and biotite (black mica). Mica is prized for its versatility; it is heat-resistant, non-toxic, and insulative, making it suitable for diverse applications.

As a naturally sourced mineral, mica fits perfectly into this trend, making it an appealing ingredient for companies focused on creating environmentally friendly, non-toxic, and cruelty-free beauty lines. Consumers are increasingly aware of the ingredients they apply to their skin, pushing cosmetic brands to embrace safer, more natural alternatives like mica pigments.

The Significance of Mica in Modern Industry

Artists often utilize mica powder to add depth and texture to their creations. Its reflective quality can amplify the richness of paints, inks, and mediums.

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.
