The mica group represents 34 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Mica sheets are also transparent to opaque, resilient, reflective, refractive, dielectric, chemically inert, insulating, lightweight, and hydrophilic. Mica also is stable when exposed to electricity, light, moisture, and extreme temperatures. [1]

The leading use of dry-ground mica in the US is in the joint compound for filling and finishing seams and blemishes in gypsum wallboard (drywall). The mica acts as a filler and extender, provides a smooth consistency, improves the workability of the compound, and provides resistance to cracking. In the paint industry, mica is used as a pigment extender that also facilitates suspension, reduces chalking, prevents shrinking and shearing of the paint film increases the resistance of the paint film to water penetration and weathering while brightening the tone of colored pigments. Mica also promotes paint adhesion in aqueous and oleoresinous formulations. The fine powders of mica have been used for various purposes, including decorations. [1]
