Abstract
The present invention is a method for producing swellable or nonswellable fluorine mica at a relatively lower temperature by heating a powdery mixture comprising 10 to 35% by weight of an alkali silicofluoride as the main component optionally together with an alkali fluoride and the balance of talc. This fluorine mica is used for pigments, etc.
