Mica's versatility leads to its use in a wide range of industries
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.
Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
Synthetic matte 2000 mesh:fine skin, matte effect.
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.
For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.
In the pharmaceutical industry, mica serves as an excipient, which is an inactive substance that serves as the vehicle for an active substance in a medication. Mica is used to aid in the manufacturing of tablets, capsules, and other formulations. Its inert nature ensures that it does not interact with the active ingredients, providing a stable and reliable means of drug delivery.
5. Food and Beverages Interestingly, natural mica flakes are also used in the food industry as a decorative element. Edible mica, often referred to as “cake glitter,” can enhance the visual appeal of cakes and confections without compromising safety.
