摘　　要：钙钛石（ＡＢＯ３）型复杂氧化物由于Ａ位、Ｂ位在适当范围内掺杂其他离子而成为性能宽广的功能材料．例如ＢａＰｂＯ３及其取代物ＢａＰｂＢｉＯ是甲烷偶联反应的催化剂［１］，ＢａＰｂＢｉＯ［２］和ＢａＫＢｉＯ［３］还具有超导性．另一方面,这些复杂氧化物的功能又?..BaKPbO and BaKPbBiO single crystals were electrodeposited on anode by the molten salt electrochemical method using KOH/KNO3 as flux. It is found that the K content decreases when the KNO3 concentration in the flux increases. On the other hand, when the KNO3 concentration in the flux is constant, the K content increases as the Bi content in the BaKPbBiO crystals increases. The magnetic susecptibility measurements show that Ba K Pb Bi O crystals are superconducting while BaKPbO crystals are not.XPS analyses reveal that the M(M=Pb,Bi)6s-O2p valence band moves toward the Fermi level when the Bi content in BaKPbBiO decreases.
