| 摘要: 计算PbO—Bi2O3—Nb2O5系化合物的声光品质因数M2在14—19范围,可与PbO·MoO3相比,故选择此系统作为开拓新声光材料的研究对象. 用X-射线相分析、电子探针、差热分析等手段,确定了一个新的化合物,其组成为3PbO·Nb2O5:Bi2O3=20:1(mole),属3PbO·Nb2O5—Bi2O3膺二元系中一稳定化合物,采用熔剂法生长了外形为六角形、深桔色的透明片状单晶.用透射Laue、Weissenberg照相及四园衍射仪,对其结晶学特征进行了研究. |

| Abstract: According to calculation method proposed by Li Deyu et al., the acousto-optic figures of merit of compounds in PbO-Bi2O3-Nb2O5 system range in 14-19, which are comparable with that of PbMoO4 crystal, widely used in practice. Therefore, selection of this system as object of investigations aims at exploring new acousto-optic materials.A new compound with composition of 3PbO·Nb2O5 and Bi2O3 in ratio of 20 and 1(mole)is found by using X-ray phase analysis, electron probe and differential thermal analysis, This compound is congruentone in pseudobinary system 3PbO·Nb2O5-Bi2O3 according to its composition. The transparent crystal of dark orange colour in form of hexagonal plate can be grown by flux method. The crystallographic studies were carried out by transmission laue, Weissenberg photographs and four circle diff-ractometer. |
