Abstract

Results of the XRD, XPS, XANES, iodometric titration and transport studies on freshly prepared Ce, Zr and Ti substituted 1-2-3 samples are reported here. It is argued that at least 2% of Ce, Zr and Ti ions go into the 1-2-3 lattice. It is found that Zr, Ti ions exist in 4⁺ valence state, Ce is in predominantly 4⁺ (mixed valence) state and valence of Cu remains unaffected on substitution.
