高质量的PbTiO_3(PZNT)和PbTiO_3(PMNT)等高质量的压电单晶已经被研究出来，并且由于它们的压电性能大大优于PZT陶瓷，自20世纪90年代末以来，它们已被用于某些换能器。综述了弛豫钛酸铅单晶的研究现状。本文还介绍了一些可能的高T_c&T；200°C单晶。合成了Pb(In1/2Nb1/2)O-3-PbTiO3(Pint)二元系和PbTiO3(Mg1/3Nb2/3)O-3-PbTiO3(Sc1/2Nb1/2)三元系单晶，并报道了它们的电学性质。此外，还介绍了一种新的发现优良压电材料的指导原则，即低分子质量B位离子的存在，它可以进入铅钙钛矿结构的Pb(B‘B“)O-3结构。
High quality piezoelectric single crystals, such as Pb(Zn1/3Nb2/3)O-3-PbTiO3 (PZNT) and Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMNT), have been investigated, and, because their piezoelectric properties are greatly superior to those of Pb(Zr1-xTix)O-3 (PZT) ceramics, they have been used for certain transducer applications since the late 1990s. The present situation for these relaxor-PT (lead titanate) single crystals is summarized. In this review, some possible high Tc > 200degreesC single crystals are also introduced. Single crystals of Pb(In1/2Nb1/2)O-3-PbTiO3 (PINT) binary system and Pb(Mg1/3Nb2/3)O-3-Pb(Sc1/2Nb1/2)O-3-PbTiO3 (PSMNT) tertiary system have been synthesized, and their electrical properties are reported. In addition, a novel guiding principle for discovering excellent piezoelectric materials, namely the presence of low molecular mass B-site ions that can enter the lead-perovskite Pb(B'B")O-3 structure, is introduced.
