It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.

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.

For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

The safety of pearlescent pigments is paramount in cosmetic formulations. Manufacturers often comply with strict regulations to ensure that these ingredients are non-toxic and suitable for skin application. As a result, pearlescent pigments are generally considered safe when used as directed, providing beautiful effects without compromising the wearer's safety.
