CALCINED mica flakes2

Calcined Micas are characterised by a sheet or plate like structure which because of its excellent basal cleavage enables particles of high aspect ratio to be produced.  These lamellar particles are flexible, tough, relatively soft, have a low co-efficient of thermal expansion, exceptional electrical properties and excellent chemical resistance.

Calcined mica flakes are made first out of mica lumps/scrap through a pulvigator and screener. Then it is heated at a temperature of 800-900 degree celsius for about half an hour.


It is used in the manufacture of pearlescent pigment, mica paper & mica tape due to its high tensile strength & dielectric properties.
