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.
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.

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.
In addition to its thermal properties, phlogopite mica is known for its impressive electrical insulating capabilities. This characteristic is invaluable in the electronics industry, where it is used in the production of capacitors and insulators. The mineral’s low dielectric constant ensures minimal energy loss during electrical transmission, thereby improving the efficiency of electronic devices. As technology advances, the demand for such materials continues to rise, solidifying phlogopite mica’s role in modern industry.
The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.

Mica is a naturally occurring mineral that is mined and processed to create a fine powder. It is renowned for its ability to reflect light, giving products a sparkling or glowing effect. In cosmetics, mica is used in everything from eyeshadows and highlighters to foundations and lipsticks. The versatility of cosmetic mica makes it a favorite among makeup manufacturers who aim to create a visually appealing, radiant finish.
For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.
1. Versatility One of the most significant advantages of epoxy mica powder is its versatility. It can be used in a myriad of applications, including art projects, resin jewelry, home decor, and industrial coatings. This adaptability makes it a popular choice among hobbyists and professionals alike.

The rise of synthetic fluorphlogopite in makeup formulations reflects a broader trend towards innovation and sustainability in the beauty industry. As consumers become more conscious of the ingredients in their cosmetics, brands are compelled to adapt and prioritize both performance and ethical sourcing. The acceptance of synthetic ingredients demonstrates a shift in consumer attitudes, where effectiveness and safety are taking precedence over traditional natural sources.

Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
