Oxide materials belonging to the Sn-Ce-O system are very interesting due to their use as solid electrolytes in fuel cells, catalysts, sensors and photoanodes in solar cells. The aim of the present work is to investigate the thermal behaviour of some tin and cerium salt mixtures. Mixtures with different representative Sn:Ce atomic ratio were prepared by classical ceramic method using SnC 2 O 4 , Ce(SO 4 ) 2 •4H 2 O and (NH 4 ) 2 Ce(NO 3 ) 6 as starting compounds. The samples were investigated by means of TG/DTA methods in flowing and static air atmosphere. SnO 2 and/or CeO 2 were identified by X-ray diffraction and IR spectroscopy in the final decomposition products, depending on the initial composition of the both series. A different crystallinity degree of the solid products was observed depending on the Ce precursor.
