摘　　要：综述了(Bi1/2Na1/2)1-xBaxTiO3系无铅压电陶瓷的最新研究进展。简述了A位非化学计量改性及几种较成功的掺杂改性方法。将A位掺杂(如La3+)、B位掺杂(如Co3+、Nb5+)以及综合掺杂(如Ce3+、Ce4+)的优缺点和掺杂机理进行了归类比较。解释了各系统中相应掺杂引起性能变化的原因,为进一步开展无铅压电陶瓷的研究提供参考。The recent development of (Bi_(1/2)Na_(1/2))_(1-x)Ba_xTiO_3-based lead-free piezoelectric ceramics was reviewed.Some useful methods to modify BNBT ceramics,such as nonstoichiometry of A-site or doping with different cations were described.Advantages or disadvantages and mechanism of doping with A-site cations (La^(3+)),B-site cations (Co^(3+),Nb^(5+)),or double cations (Ce^(3+) and Ce^(4+)) were compared.And the causes of property differences were described.This review might be helpful for further study of lead-free piezoelectric ceramics.
