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.

4. Screening The ground mica is screened to ensure uniform particle size. Proper sizing is crucial for achieving the desired shimmer and appearance in culinary applications.

What are the uses of mica

Furthermore, while mica itself is not toxic, some individuals may experience allergic reactions to certain pigments or additives used alongside mica. For this reason, it is essential to read labels carefully, especially for those with sensitive skin or known allergies.

Moreover, the versatility of pearls allows for a wide range of color combinations. Car owners can choose from a spectrum of colors, from soft pastel shades to vibrant hues, ensuring that their vehicle can stand out in a crowd. The unique look of pearl finishes is perfect for those who want to express their individuality and taste beyond the standard color selections offered by manufacturers.
