The unique layered structure of mica allows it to be easily cleaved into thin, flexible sheets. This property is not just aesthetic; it provides significant functional advantages. For instance, the mica sheets can withstand high temperatures without losing their integrity, making them ideal for thermal insulation applications. Mica is also an excellent electrical insulator due to its high dielectric strength and resistance to electrical conductivity, which is particularly beneficial in the manufacturing of electrical components.

1. Coloring Agent One of the primary uses of mica powder in resin is as a coloring agent. It offers a vibrant palette to choose from, allowing artists to create unique color combinations and effects. By mixing mica powder into resin, crafters can achieve translucent, opaque, or shimmering finishes, enhancing the overall visual appeal of their work.

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 mica industry is undergoing profound changes. With the help of emerging industries, the mica industry will be a large market of more than 10 billion.

5. Eco-Friendly Option Naturally sourced, mica is often viewed as a more environmentally friendly alternative compared to synthetic additives. As the automotive industry moves towards sustainability, the demand for natural and biodegradable materials continues to grow.

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