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 variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

Moreover, matte mica powder generally poses little risk for skin irritation, making it suitable for sensitive skin types. However, as with any cosmetic ingredient, it’s pertinent to choose high-quality formulations that minimize the risk of allergic reactions. Always conducting a patch test before fully integrating new products into your beauty routine can help ensure compatibility with your skin type.

Mica is a new non-metallic crystal material, a national key new material, with heat insulation, insulation, high temperature resistance characteristics, is an important material in aerospace, rail transit, nuclear power, wind power, aircraft carriers and other high-tech fields, but also electrical equipment, wire and cable, household appliances indispensable insulation material, in the national economy and national defense construction plays an important role.

Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

One of the key factors driving the adoption of mica pigments in natural and organic cosmetics is their ability to add color and texture without relying on synthetic dyes and pigments. Many synthetic colorants are derived from petrochemicals or contain harmful substances such as parabens, phthalates, and artificial fragrances, which can be irritating to the skin or harmful in the long term. Mica, on the other hand, is a mineral that is naturally abundant and free from such synthetic chemicals.

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

For instance, mixing a pigment powder with a clear lip gloss creates a vibrant lip color, while blending it with a facial moisturizer can yield a subtle, glowing highlight. The potential for customizing products means that makeup lovers can cultivate a personal style that reflects their individuality.

In 2022, Lingshou Huajing Mica Co., Ltd. launched cosmetic grade mica powder. The flake structure of mica powder can lock the water on the surface of the skin, forming a protective film to effectively prevent water loss. Its unique gloss and reflection effect add natural and charming luster to the skin, and mica powder also has a certain sunscreen effect. To a certain extent, it can reduce the damage of ultraviolet rays on the skin, protect the skin from the external environment, and prevent sunburn.

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

1. Cosmetics Mica powder is most commonly used in the cosmetics industry. Its light-reflecting properties provide a glow that enhances skin tones, making it an ideal ingredient for foundations, blushes, eyeshadows, and lip products. Many brands now prioritize natural mica in their formulations to cater to the growing demand for clean beauty products.
