Mica flakes are extensively used in the cosmetics industry, where they are added to a wide range of products such as eyeshadows, lipsticks, nail polishes, and body glitter. The flakes provide a sparkling effect and enhance the visual appeal of these products.

In addition to cosmetics, mica flakes find applications in industries such as automotive, electrical, construction, and paints and coatings. They are often used as a filler or additive in the production of plastics, rubber, asphalt, and concrete. Mica's heat resistance and ability to withstand high temperatures make it a valuable ingredient in insulation materials, electrical equipment, and fireproofing.
