Mica is a hydrated phyllosilicate mineral of aluminium and potassium with formula KAl(F, OH), or (KF) (AlO) (SiO). Muscovite can be cleaved into very thin transparent sheets that can substitute for glass, particularly for high-temperature applications such as industrial furnace or oven windows.
It is also used in the manufacture of a wide variety of electronics and as a filler in paints, plastic, and wallboard. Our monthly supply of these mineral ranges from 1000-2000MT.

Item4: mica/mika:
Mica is a group of naturally occurring minerals known for their ability to split into thin, flexible layers. It is commonly used in various industries due to its insulating properties, heat resistance, and electrical conductivity. Mica is often found in shades of silver, gold, and brown and is used in products like cosmetics, paints, electronics, and construction materials. It also serves as a dielectric material in electrical applications and as a filler in plastic and rubber manufacturing.
Mica powder is a non-metallic mineral, containing a variety of components, of which the main SiO2, the content is generally about 49%, Al2O3 content is about 30%.
Mica powder has good elasticity and toughness. It is widely used in electrical appliances, welding rods, rubber, plastics, paper, paint, coatings, pigments, ceramics, cosmetics, new building materials and other industries
Mica Powder in various forms is obtained by grinding/breaking mica scrap, which is a slow, costly and extremely complicated process, because of the scrap being tough and having a plate like structure. Meticulous care and precaution has to be taken so that there is no deterioration of its natural brilliance, colour and properties. Sun Minerals offer a suitable range of pure and stable mica powder that is a typical lamellar particle structure. This structure proves to be beneficial wherever a high rate of resistance against chemicals, heat and ultra violet light is required. Mica powder therefore is widely used in paint industry. Our factories are fully equipped with latest different pulverisers for processing varieties of mica powder.
