摘要：
Using 0.76Bi(0.5)Na(0.5)TiO(3)-0.24SiTiO(3) which approaches the morphotropic phase boundary of Bi0.5Na0.5TiO3-SiTiO3 as base composition and adding Bi(Mg2/3Nb1/3)O-3, (1-x)(0.76Bi(0.5)Na(0.5)TiO(3)-0.24SiTiO(3))-xBi(Mg2/3Nb1/3)O-3 dielectric ceramics were prepared by a traditional solid-state reaction method, and their structural, dielectric, and electrical energy storage properties were studied comprehensively. Bi(Mg2/3Nb1/3)O-3 disturbs the long-range ferroelectric ordering, thus remanent polarization decreases rapidly. As a result, the electrical energy storage properties improve greatly in the ternary system.
