Mica

Mica, a mineral with a layer structure, has been used by humans for millennia: originally for cosmetic purposes, and in the early 20th century as the acoustic membrane for gramophones. Easy to split, transparent, chemically and thermally resistant mica discs are used to this day as a glass substitute in furnaces, chemical plants and industrial applications.

Main areas of application

  • as effect pigment in paints and plasters
  • for sound absorption in the automotive sector
  • as additive for corrosion protection coatings
  • as release agent in the rubber industry
  • to improve the mechanical properties

Mica is a collective name for aluminium silicate minerals that set themselves apart with a unique combination of properties that make them versatile in application. Different categories of mica have been defined according to the chemical composition; light muscovite mica and dark phlogopite mica in particular are important for industrial applications. Due to its shimmering appearance, mica is also used as an effect pigment in plaster, paints and coatings. .

Iron mica however is chemically classified as an iron oxide and mainly used as a corrosion protection pigment.
