我们详细比较了Ba（SnTi）O3-x（巴卡）TiO 3系统中的四方-斜方（T-R）相界和Ba（SnxTi 1 −x）O3系统中的四方-斜方（T-O）相界的物理性质。对比结果表明，T-R相界比T-O相界对压电性的增强作用更明显。这种差异被认为是源于极化旋转的不同各向异性，不同的弹性软化和T-R和T-O相界之间不同的畴壁贡献。
We made a detailed comparison of physical properties between the tetragonal-rhombohedral (T-R) phase boundary (in the Ba(SnTi)O3-x(BaCa)TiO3 system) and the tetragonal-orthorhombic (T-O) phase boundary (in the Ba(SnxTi1−x)O3 system). The contrasting results suggest that the T-R phase boundary enhances the piezoelectricity more significantly than the T-O phase boundary. Such difference is considered to stem from the dissimilar anisotropy for polarization rotation, the different elastic softening and the different domain wall contribution between T-R and T-O phase boundaries.
