弛豫反铁电材料(Pb，La)(Zr，Sn，Ti)O_3(PLZST)的组成接近准同型相界，表现出优异的电性能。然而，材料的不均匀熔融限制了PLZST晶体的生长。在50wt%PbO-PbF_2-B_2O_3为溶剂的助熔剂溶液中，用铂丝诱导PLZST晶体生长。得到的PLZST单晶是光学透明的，呈淡黄色。规则矩形的晶体尺寸从0.5 mm到1 mm不等。PLZST单晶具有四方相结构。用电感耦合等离子体原子发射光谱仪测定了晶体中的元素含量。结果表明，生长的晶体成分与初始成分有一定的偏差。单晶在115°C和182°C有两个介电峰，分别对应于反铁电-铁电和铁电-顺电相变。原始晶体的介电数据表明，在182C附近有典型的弛豫行为，弛豫因子n为1.49642。
Relaxor antiferroelectric (Pb,La)(Zr,Sn,Ti)O3 (PLZST) with the composition near the morphotropic phase boundary shows excellent electrical properties. However, the crystal growth of PLZST is limited by the incongruent melting of the materials. Crystal growth of PLZST was induced by a platinum wire in the flux solution with 50 wt% PbO‐PbF2‐B2O3 as a solvent. The obtained PLZST single crystals are optical transparent with light yellow color. The size of the crystals in regular rectangular shape varies from 0.5 mm to 1 mm. The PLZST single crystals exhibit tetragonal phase structure. The element contents of the crystals were measured by inductively coupled plasma atomic emission spectrometry. The results show that the composition of as‐grown crystals is a little bit deviated from the starting composition. The single crystals show two dielectric peaks at 115 °C and 182 °C, corresponding to antiferroelectric‐ferroelectric and ferroelectric‐paraelectric phase transitions. The dielectric data of as‐grown crystals indicate there is typical relaxor behavior near 182 °C. The value of relaxor factor n is 1.49642.
