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.

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.

In highlighters, for example, mica particles catch and reflect light, giving the skin a dewy, illuminated look. This is especially popular in products designed for achieving a glowing complexion. Mica is used to give eyeshadows their shimmer and shine, allowing for a metallic or pearlescent finish that enhances the eyes' natural contours. The ability to create these visually striking effects makes mica an indispensable ingredient in many cosmetic products.

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.

Mica is a silicate mineral composed of multiple layers of silicate sheets that can be separated into thin, flexible sheets. This property, along with excellent thermal resistance, electrical insulation capabilities, and resistance to moisture, makes mica particularly valuable. It is widely used in products such as makeup, insulation materials for electrical devices, and as a filler in various applications.
