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.

2. Mechanical Strength The layered structure of mica contributes to its flexibility; however, natural mica can be fragile. In contrast, synthetic fluorphlogopite exhibits enhanced mechanical strength, providing greater resistance to breakage and wear. This property renders it an excellent choice for applications in environments subject to mechanical stress.

Mica is prized for its unique lamellar structure and reflective properties. When incorporated into paint formulations, mica creates a shimmering effect that enhances the depth and richness of colors. This glittering finish not only attracts buyers but also provides a premium feel to the vehicle. Mica-pigmented paints can produce a wide array of effects, from subtle elegance to dynamic, eye-catching visuals. Automotive manufacturers often choose mica-based paints to differentiate their vehicles in a competitive market, as these coatings can produce unique color variations that change with light and angle, creating an engaging and dynamic appearance.

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.

At its core, pearlescent pigment powder consists of tiny, flat particles that reflect and refract light in a way that produces a unique, lustrous finish. These pigments are often made from natural materials like mica or synthetic substances, and they are coated with various metallic oxides to enhance their optical properties. The result is a spectrum of colors that can change depending on the angle from which they are viewed, creating a dazzling effect that is sought after in many applications.

The Versatile World of Decorative Mica Sheets

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.
