The variation of dielectric, ferroelectric and piezoelectric characteristics of BaZrO₃–modified (Ba_0.85Ca_0.15)TiO₃ ceramics, (1-x)(Ba_0.85Ca_0.15)TiO₃-xBaZrO_3, have been investigated together with the structure evolution. The crystal structure at room-temperature varies from tetragonal to metrically cubic through orthorhombic and rhombohedral, and the morphotropic phase boundary (MPB) is determined around x = 0.12 where the significantly enhanced dielectric, ferroelectric and piezoelectric characteristics are achieved. With increasing x, the present ceramics indicate the crossover from normal to diffused and relaxor ferroelectric, and the evolution process is explored systematically.

BaZrO ₃改性(Ba _0.85 Ca _0.15 )TiO ₃陶瓷、(1-x)(Ba _0.85 Ca _0.15 )TiO ₃ -xBaZrO ₃的介电、铁电和压电特性的变化_，与结构演化一起进行了研究。室温下的晶体结构从四方到公制立方到正交和菱面体，并且同形相界 (MPB) 确定在 x = 0.12 附近，其中实现了显着增强的介电、铁电和压电特性。随着 x 的增加，目前的陶瓷表明从正常到扩散和弛豫铁电体的交叉，并系统地探索了演化过程。
