Mica
Mica is a group of minerals that exhibits a layered or platy structure. Commercially important mica minerals are muscovite (potash or white mica) and phlogopite (magnesium or amber mica). It possesses highly perfect basal cleavage due to which it can easily and accurately split into very thin sheets or films of any specified thickness. It has a unique combination of elasticity, toughness, flexibility and transparency. It possesses resistance to heat and sudden change in temperature and high dielectric strength. It is chemically inert, stable and does not absorb water.
 
Uses
Construction Sector Mica scrap/ground mica is used in jointing cement for gypsum boards, asphaltic roofings and damp-proof seal, reinforcing filler in plaster and insulation boards, bricks, slabs and tiles.
Welding Electrode Our Dry-ground mica powder is highly popular in the flux coating with arc welding electrode manufacturers
Paints Mica is supplied in the form of powder used as filler and as an extender
Drilling  Mica is added to drilling fluids to get off the lost circulation zones. The platy structure of mica facilitates the overlapping of particles to form a tight layer or wall, thereby preventing further fluid loss.
Rubber Industry Ground mica is used in the rubber industry as a dusting agent and as inert filler in the production of rubber.
Plastic Industry Mica is used as a filler and reinforcer in thermoplastics to improve the electrical properties, flexural strength & modulus, stiffness, heat deflection temperatures and resistance.
Cosmetic Applications Dry-ground mica powder is used in small quantities in cosmetic applications due to its high resistance to the effect of the sun rays, moisture, gases, water and other chemicals,
Decorative Coating Dry-ground mica powder in small quantity is also used to improve the decorative coating and luster of wallpaper, printing and ceiling papers, etc.
Foundries Small quantities of scrap mica/ground mica are also used in industries like foundries as coating to foundry cores and moulds, as a dry lubricant to prevent hot bearings from seizing up.
