    Answer:

Mica has been used in many industries:

  • Primary use: in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves workability, and prevents cracking. 
  • Paint & coating industry: a pigment extender that facilitates suspension due to its light weight and platy morphology. It reduces checking and chalking, prevents shrinkage and shearing of the paint film, provides increased resistance to water penetration and weathering, and brightens the tone of colored pigments.
  • Well-drilling industry: an additive to drilling "muds." 
  • Electronic and electrical industries: electrical insulators in electronic equipment, thermal insulation, gauge "glass", windows in stove and kerosene heaters, dielectrics in capacitors, decorative panels in lamps and windows, insulation in electric motors and generator armatures, field coil insulation, and magnet and commutator core insulation. 
  • Plastic industry: used as an extender and filler and also as a reinforcing agent due to its ability to prevent lost circulation by sealing porous sections of the uncased drill hole.
  • Rubber industry: an inert filler and as a mold lubricant in the manufacture of molded rubber products, including tires.
