摘要点缺陷对晶体的物理性质有重要影响。缺陷的存在可能会导致晶体变色并增加其导电性，使这些晶体的技术应用变得困难甚至不可能。本文给出了钛酸铅晶体中点缺陷形成的几种可能性。这些缺陷的存在可能与非化学计量比和杂质有关。这些研究的目的是确定获得高质量PbTiO_3单晶的工艺条件。用“助熔剂”法从PbO-TiO2B2O3溶液中获得了晶体。
Abstract Point defects exert an important influence on the physical properties of crystals. The presence of defects may cause colouration of crystals and increase in their electric conductivity making technical application of these crystals difficult or even impossible. In this paper several possibilities of point defects formation in PbTiO3 crystals are given. The presence of these defects may be associated both with nonstoichiometry and with impurities. The aim of these studies was to determine the technological conditions for obtaining high quality PbTiO3 single crystals. Crystals were obtained by the “flux” method from PbO-TiO2-B2O3 solution.
