摘　　要：Phase diagram of(1-x)Na_(0.5)K_(0.5)NbO_(3-x)(Bi_(0.5)Na_(0.5))ZrO_(3)solid solution has been established from dielectric constant measurements and structure analyses.It is found that with increasing x,the C-T phase transition temperature T_(C-T)and the T-O phase transition temperature T_(T-O)decrease,while the O-R phase transition temperature T_(O-R)increases.T_(T-O)of NKN-xBNZ is much different from that of NKN-xBZ solid solution.The result could be mainly elucidated by the hybridization between the A-site ion and oxygen.
