What is mica and where it is used?

Mica is a natural mineral composed of silicate minerals that exhibit a layered structure, allowing them to be split into thin, flexible sheets. It is commonly used in a variety of applications, including cosmetics (as a colorant and for its shimmering effect), electronics (as an insulator in capacitors and other components), and construction materials (such as joint compounds and roofing). Its unique properties, including heat resistance and electrical insulation, make it valuable across diverse industries.
