采用磁通法生长x(Bi，K)TiO3 - (1 - x)(Bi,Na)TiO3（0.11≤x≤0.47）单晶，并在25℃下沿< 100 >立方方向研究其极化和压电性能。粉末x射线衍射数据的Rietveld分析提供了该体系的初步相图：当x≤0.22时为菱形R3c，当0.22 < x < 0.3时为伪体，当0.3≤x时为四边形P4mm。压电应变特性表明，晶体（x = 0.38）具有极高的压电应变常数637 pm/V。
Single crystals of x(Bi,K)TiO3 - (1 - x)(Bi,Na)TiO3 (0.11 ≤ x ≤ 0.47) were grown by a flux method and their polarization and piezoelectric properties were investigated along 〈100〉cubic at 25°C. Rietveld analysis of powder X-ray diffraction data provides a tentative phase diagram in this system: rhombohedral R3c for x ≤ 0.22, pseudocubic for 0.22 < x < 0.3 and tetragonal P4mm for 0.3 ≤ x. Piezoelectric strain properties show that the crystals (x = 0.38) exhibited an extremely large piezoelectric strain constant of 637 pm/V.
