Mica is the term for a large group of sheet silicates that can be parted into flexible or brittle sheets. Includes the True Micas or Common Micas (with monovalent interlayer cations, e.g. muscovite, paragonite, ephesite) and the Brittle Mica s (with divalent interlayer cations, e.g. margarite, clintonite). Also known as the " mica family". Mica Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals , known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity. There are 37 different mica minerals . The most common include: purple lepidolite, black biotite, brown phlogopite and clear muscovite. Mica , which is essentially a compound of silicate minerals , is comprised of closely related materials that have perfect basal cleavage. They belong to the category of principal rock-forming minerals and are found in various categories like sedimentary, igneous, and metamorphic. Mica is a naturally occurring mineral known for its unique physical properties, including its ability to split into thin, flexible sheets. This versatility makes mica invaluable across various industries, from electronics to cosmetics. The global distribution and mining of mica reflects its widespread industrial use. Mica deposits are found in significant quantities across different continents, emphasizing its role in economic and industrial developments worldwide. Understanding the origins ...
