The effect of dry grinding on the structure of talc

The effects of dry grinding on the textural and structural properties of a well crystallized talc are studied. Intense mechano-chemical effects occur even at short grinding times due to the low hardness of talc. The physico-chemical and structural alterations are evaluated by BET surface area, particle size, porosity, CEC, solubility, DTA-TGA, XRD and IR techniques. An increase in the surface
