摘    要：通过传统熔体冷却方法确定了高Bi₂O₃低B₂O₃含量的PBO－Bi₂O₃－B₂O₃系统形成玻璃的最少B₂O₃引入量;利用X射线衍射分析和红外光谱分析方法研究了由PB₃O₄,Bi₂O₃单一氧化物、高Bi₂O₃含量的PBO－Bi₂O₃二元系统及高Bi₂O₃低B₂O₃含量的PBO－Bi₂O₃－B₂O₃三元系统经熔融冷却而获得物质的结构特点,探讨了少量B₂O₃的引入对该三元系统形成玻璃的作用和形成无定形结构的可能机制。

Abstract: The minimum of addition of B₂O₃ oxide for glass forming in the PbO- Bi₂O₃-B₂O₃ systemcontaining higher Bi₂O₃ was determined by conventional melt cooling route. X-ray diffractionand IR methods were used to study the structure features of these substances gained by melt-ing Bi₂O₃ or Pb₃O₄ single oxide,PbO-Bi₂O₃ binary system oxides and PbO-Bi₂O₃-B₂O₃ ternarysystem oxides.The effects of addition of B₂O₃ on the glass forming in the PbO-Bi₂O₃B₂O₃ system were discussed.The possible mechanism of forming amorphous structure for theternary system was presented.
