mica

• Mineral composto de silicatos hidratados de alumínio ou potássio, que cristaliza em formas capazes de se dividir em lâminas muito finas, usado como isolante elétrico devido à sua resistência elétrica.

A mineral consisting of hydrous silicates of aluminum or potassium that crystallizes in forms allowing perfect cleavage into very thin leaves, used as a dielectric due to its electrical resistance.

   • Mica is commonly used in electrical capacitors due to its insulating properties.
   • The rock contained large flakes of mica that sparkled in the sunlight.
   • Geologists identified the mineral as muscovite, a type of mica.
