Grinding produced a profound structural alteration, resulting in increasing amorphization. Increasing the intensity of grinding resulted in acceleration of the mechanically induced amorphization of the pyrophyllite structure. The pyrophyllite phase was transformed into its anhydride phase during the process of the prolonged grinding.

The.''study of the grinding effects on clay minerals is a subject of great ~nterest because is a very common process in the industry and re#173; search laboratory.
01/06/1994#0183;#32;Intense mechanochemical effects occur even at short grinding times due to the low hardness of talc. The physicochemical and structural alterations are evaluated by BET surface area, particle size, porosity, CEC, solubility, DTATGA, XRD and IR techniques. An increase in the surface area accompanied with agglomeration of particles is observed.
