The results of investigations of 3 calcium bentonites, activated by sodium carbonate, applied in the foundry industry as binding material for moulding sands are presented in the paper. Investigations were performed by the thermal analysis (TG) method. The occurrence of the dehydration and dehydroxylation process was confirmed in all tested bentonites.
