| 摘 要： | 采用示差扫描量热法(DSC)、热膨胀曲线法及交流阻抗谱法对Bi2Co0.1V0.9O5.35-δ陶瓷的相变过程进行了研究。研究结果表明,Bi2Co0.1V0.9O5.35-δ陶瓷在420~500℃温度范围内产生了相变,这种相变是温度发生变化时钒氧八面体层内氧空位排列的有序-无序转变引起的。

| Abstract: | The order-disorder phase transition in Bi2Co0.1V0.9O5.35-δ ceramics was characterized by DSC,linear thermal expansion measurement and ac impedance spectroscopy.The results indicate that a order-disorder phase transition was observed in the range of 420～500 ℃,which lies in the various disordering degree of oxygen vacancies in the vanadate layer. |
