Mica is a group of silicate minerals that are characterized by their layered structure. The most common types of mica used for powder include muscovite and phlogopite. These minerals are found in igneous and metamorphic rocks and are known for their excellent heat resistance and electrical insulation. Once mined, mica is processed and ground into a fine powder that can be used either in its natural state or enhanced with pigments and additives for a spectrum of colors.

Trustworthiness and reputation in mica production are underscored by China’s stringent quality control measures. The implementation of international standards ensures that Chinese mica products meet the highest global criteria, instilling confidence among international clients. This dedication to quality fortifies China’s authoritative position in the global mica market.

- Mixing Always blend mica pigments thoroughly with your chosen medium to ensure even distribution and avoid clumping. Experimenting with different ratios can yield exciting new colors and effects.

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.
