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.

Choosing high-quality mica powder for resin is essential for achieving the best results in your resin projects. Low-quality powders can result in uneven mixing, fading, or discoloration over time, compromising the aesthetic quality of your work. High-quality mica powder for resin, on the other hand, provides vibrant, lasting color and a smooth, consistent finish.

In addition, lepidolite and ferrolepidolite can also be used as mineral raw materials for extracting lithium.

4. Sealants and Adhesives Mica powder improves the performance of sealants and adhesives by enhancing their flexibility and resistance to temperature fluctuations. This is essential for ensuring the longevity of joints and seals in automobiles.

Mica is a naturally occurring mineral that has been used for centuries in beauty products thanks to its rich luster and brilliance. Composed of finely layered silicate minerals, mica is often processed into a fine powder and used in various cosmetics, including eyeshadows, blushes, and of course, lip gloss. What makes mica powder particularly appealing is its ability to reflect light, creating a shimmering, sparkling effect that catches the eye.
