mica

• Minéral composé de silicates hydratés d'aluminium ou de potassium, se clivant en feuillets très minces et flexibles, utilisé comme isolant électrique et thermique.

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 (minéral)

   • 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.
