MICA

Mica minerals are major rock forming minerals found in gneiss, schist and granite. The mica group includes muscovite mica and biotite mica.

Industrial Application:

Mica is used as a pigment extender in the paint and coating industry that also facilitates suspension, reduces chalking, prevents shrinking and shearing of the paint film, increases resistance of the paint film to water penetration and weathering, and brightens the tone of coloured pigments.

Mica powder is used as filler in rubber goods, lubricant, and, to some extent, in Plastic industries. It is widely used in fire extinguishers and insulation.

It is also used in the manufacture of Roofing material, Welding rod, Wall-paper, Lamp chimneys, shades, etc.
