Where is sheet muscovite mica used?
Sheet muscovite is an excellent insulator, and that makes it suitable for manufacturing specialized parts for electrical equipment. Scrap, flake, and ground muscovite are used as fillers and extenders in a variety of paints, surface treatments, and manufactured products.
Where is muscovite mica found in the world?
The world's chief deposits of mica are found in India at Bihar and in the Nellore district of Madras. Over 50% of the mica used today comes from these two regions. Other major producers are Belgium, Brazil and China.
What is the difference between muscovite and biotite mica?

What are the two types of mica?
There are several varieties of mica, but the three primary varieties are, muscovite, a hydrated silicate of aluminum and potassium; phlogopite, which is a magnesium bearing mica; and biotite, a ferro-magnesium variety.
What is mica called?
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 a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate mineralssilicate mineralsGeneral structure A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms. In most minerals in the Earth's crust, each silicon atom is the center of an ideal tetrahedron, whose corners are four oxygen atoms covalently bound to it.https://en.wikipedia.org › wiki › Silicate_mineralSilicate mineral - Wikipedia, known as sheet silicates because they form in distinct layers.
