Mica is a group of silicate minerals known for their sheet-like structure and excellent cleavage properties. These minerals are commonly found in igneous and metamorphic rocks and are characterized by their ability to be split into thin, flexible sheets. Mica is widely used in various industries, including electronics, cosmetics, and construction due to its insulating properties and resistance to heat. There are several types of mica, with Muscovite and Biotite being the most common. Muscovite is often used in electrical insulators and as a filler in products, while Biotite is typically found in granite and other rocks. The unique properties of mica make it a valuable resource in many applications.
