Interaction of rhodium with chloro-complexes of palladium at elevated temperatures

Powders of superfine rhodium with mono- and polyblock structures were obtained. The processes of coarsening of nanodispersed rhodium crystallites were investigated in detail at 130 and 180 °C. In muriatic solutions, dissolution of metal rhodium was found to occur. It was connected with the presence of chemisorbed oxygen at its surface. The possibility of formation of rhodium-palladium substitutional solid solutions on the electrolytic precipitation was fi rstly established.
