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.

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

6. Cooling and Unmolding Allow the soap to cool and harden completely. This may take a few hours or overnight. Once fully set, gently remove your soap from the molds.

Moreover, the mica industry has been marred by ethical concerns, particularly concerning child labor. Mica is often mined in developing countries where labor laws may be inadequately enforced. Reports of children working in dangerous conditions to extract mica for very low wages have raised significant concerns among consumers and advocacy groups. Companies must ensure that their supply chains are free from child labor and exploitation, promoting ethical sourcing practices that respect workers' rights.

It’s important to note that when using pearl pigments in food, one should ensure that the pigments are food-grade and safe for consumption. This has led to the development of various brands specializing in edible versions of these pigments.

The mica powder of HUAJING has the advantage of extremely narrow particle size, and the particle size specifications are complete, such as: 2000 mesh, 1250 mesh, 800 mesh, 400 mesh, 120 mesh, etc. The skin feeling is exquisite.

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

In the realm of electronics, phlogopite mica is essential in the production of insulators for capacitors and other electronic components. Its dielectric properties and high thermal resistance allow for efficient heat dissipation, preventing overheating in electronic devices. Furthermore, its role as an insulator makes it critical in high-voltage applications, ensuring safety and reliability.
