用介电、热释电和D-E特性研究了Sr_x（Na_（0.5）Bi_（0.5））_（1-x）TiO_3固溶体的相变。在该体系的组成为0 × 10 ~（-5）范围内观察到一个中间反铁电相。这些组合物在高温下经历铁电-反铁电-顺电的转变序列。反铁电相变温度和居里点随SrTiO 3浓度的增加而单调下降。
Phase transitions in the solid solution Srχ(Na0.5Bi0.5)l-χTiO3have been studied by dielectric, pyroelectric and D-E characteristic measurements. An intermediate antiferroelectric phase has been observed in the composition range of 0 ⩽ χ ⩽ 0.5 of this system. These compositions undergo a ferroelectric-antiferroelectric-paraelectric sequence of transitions at elevated temperatures. The antiferroelectric phase transition temperature and Curie point decrease monotonically with increasing SrTiO3concentration.
