Thermal behavior of talc samples (from locality Puebla de Lillo, Spain) were characterized by emanation thermal analysis (ETA), DTA and TG. The ETA, based on the measurement of radon release rate from samples, revealed a closing up of surface micro-c

The effect of sonication on the dehydroxylation process of antigorite has been studied using TG-DTG and FTIR spectroscopy. Sonication process causes important particle-size reductions, while the structure of the antigorite is preserved as shown by XR
