Abstract : Sodium tungsten bronzes incorporating a second transition metal (Nb, Ta, V, Co and Zr) were prepared. Techniques of chemical analysis have been developed and some bronzes analyzed. X-Ray diffraction studies show these bronzes to be mixed bronzes in which the second transition metal partly replaces tungsten in the lattice. Oxygen evolution and dissolution were studied on the mixed bronzes and some pure bronzes. pH and oxygen partial pressure dependencies have been obtained. The data are discussed.
