Crystal Structure and Characterization of La 1-x Bi x MnO 3+δ

The La 1- x Bi x MnO 3+δ ( x =0.0-0.5) solid solutions were synthesized using three different methods: solid-state synthesis, citrate-nitrate combustion synthesis. All compositions crystallize in a rhombohedral perovskite structure, independent of the synthesis method. Two ranges with linear tempera...

Description
Summary:The La 1- x Bi x MnO 3+δ ( x =0.0-0.5) solid solutions were synthesized using three different methods: solid-state synthesis, citrate-nitrate combustion synthesis. All compositions crystallize in a rhombohedral perovskite structure, independent of the synthesis method. Two ranges with linear temperature dependence of the unit cell parameters have been observed during in-situ heating X-ray powder diffraction experiments. The transition between the two ranges occurs at 730°C and is explained by chemical expansion at high temperatures. The chemical compatibility between the obtained solid solutions and bismuth-containing electrolytes (Bi 4 V 1.7 Fe 0.3 O 11 , Bi 13 Mo 5 O 34 and Bi 3 Nb 0.8 W 0.2 O 7.1 ) was studied. Interaction between these materials has been observed at temperatures higher than 600°С.
