Abstract

Non-integer A and B site cation valence perovskite oxides with bismuth and niobium cations were synthesized. Using the tolerance factor, some single phase perovskite oxides were obtained. For the A^1+xB^5-xO₃ type (Bi_x/2K_-x/2+1)(Ti_xNb_1-x)O₃ ceramics, the Curie temperature increased from approximately 200 to 350 °C with increasing x from 0.5 to 0.9. These results were discussed with the Abrahams relations.
