PRODUCTION OF SYNTHETIC MICA

PROBLEM TO BE SOLVED: To produce synthetic mica having satisfactory crystallinity and capable of pulverization to synthetic mica powder having a high aspect ratio by melting starting material for synthetic mica by an internal combustion type melting method, discharging the resultant melt into a specified vessel and crystallizing it in the vessel. SOLUTION: Starting material for synthetic mica is melted by an internal combustion type melting method and the resultant melt is discharged into a heat insulating vessel and crystallized in the vessel to produce the objective synthetic mica. The vessel is preferably preheated before the melt is discharged into the vessel. The vessel preferably has an air layer in the wall and the especially pref. heat conductivity of the vessel is
