摘要：

The crystal structure change of the solid solution BiCo1-xFexO3 was investigated in order to determine the phase boundary between tetragonal BiCoO3 and rhombohedral BiFeO3. It was found that BiCo1-xFexO3 with x = 0 to 0.6 had tetragonal BiCoO3 structures, while those with x = 0.8 to 1 had rhombohedral BiFeO3 structures at room temperature. The monoclinic root 2a x root 2a x a phase was found for the x = 0.7 sample. The tetragonal-to-cubic phase transition was first observed at around 700-850 degrees C in Bi-based perovskite for the x = 0.8 sample.
