摘要

在x=0-0.1的范围内，研究了一种能使(Bi0.5Na0.5)(1-x)BaxTiO3陶瓷的压电性能最大化的最佳成分，覆盖了体系的菱形到四方相区。在无杂质相的情况下，根据Ba含量形成了两种不同晶体对称性的钙钛矿结构。在x=0.05~0.08范围内，存在一个分菱形和四边形相区范围的相变边界。压电性能方面，在测试范围内，压电常数d33和机电耦合系数Kp在x=0.065处达到峰值，分别为192 pC/N和34%，说明(Bi0.5Na0.5)(1-x)BaxTiO3压电陶瓷的最佳组成为x=0.065。

Composition Dependent Piezoelectric Properties of Pb-free (Bi0.o5N0o 5)1-x) BaxTiO3 Ceramics

An optimum composition for maximizing piezoelectric properties of (Bi_0.5Na_0.5)_(1-x)Ba_xTiO₃ ceramics was investigated within the range of x=0-0.1 covering rhombohedral to tetragonal phase regions of the system. A perovskite structure with two different crystal symmetries depending on the Ba content was formed with no impurity phases. A range of morphotropic phase boundary dividing rhombohedral and tetragonal phase regions was found to exist at x=0.05~0.08. As for piezoelectric properties the piezoelectric constant (d₃₃) and the electromechanical coupling factor (K_p) showed a peak value at x=0.065 within the range tested, which was 192 pC/N and 34%, respectively, implying x=0.065 as an optimum composition for piezoelectric (Bi_0.5Na_0.5)_(1-x)Ba_xTiO₃ ceramics.
