About mica
mica is the group for a number of complex hydrous potassium silicate minerals with differing chemical compositions and physical properties.crystals mica has excellent basal cleavage and split easily into tough flexible sheets.important mica minerals are muscovite and phlogophite.
mica has unique electrical and thermal insulating properties and its mechanical properties which allow it to be cut, punched, or stamped to close tolerances.it has a very low conductivity and power loss, and a very high dielectric constatnt which have made it indispensable for electric and electronic industries.india is the largest producer of best quality ruby(uscovite) sheet mica in the world.
