A new kind of bismuth borate glasses based on P₂O₅-V₂O₅-Bi₂O₃-B₂O₃ system is prepared by the modified melt-quenching method. The conformation of the amorphous phase in the sample was done through X-ray diffraction analysis. The density, molar volume, oxygen molar volume and oxygen packing density in the glass network were investigated according to the substitution of Bi₂O₃ by B₂O₃. The density and the molar volume decreased in parallel with B₂O₃ content increase. Simultaneously, oxygen molar volume values decreased while the oxygen packing density values increased. It is found that B₂O₃ is the component that contributes most to increase the thermal stability of the glasses, while Bi₂O₃ is the most contributing oxide to decrease the thermal stability. The structural origins for the variations of the thermal stability with the glass composition are discussed based on the Fourier-transform infrared (FTIR) spectrometry measurement FTIR spectroscopy reveals that the incorporation of V₂O₅ in the glass network helps to convert the structural units of [BO₃] into [BO₄].

通过改进的熔融淬火法制备了一种新型的基于P ₂ O ₅ -V ₂ O ₅ -Bi ₂ O ₃ -B ₂ O ₃体系的硼酸铋玻璃。样品中非晶相的构象是通过X射线衍射分析完成的。根据Bi ₂ O ₃被B ₂ O ₃取代，研究了玻璃网络中的密度，摩尔体积，氧摩尔体积和氧堆积密度。密度和摩尔体积与B ₂ O ₃平行下降内容增加。同时，氧摩尔体积值减少而氧堆积密度值增加。发现B ₂ O ₃是最有助于增加玻璃的热稳定性的组分，而Bi ₂ O ₃是最有助于降低热稳定性的氧化物。基于傅立叶变换红外（FTIR）光谱测量，讨论了热稳定性随玻璃成分变化的结构起源。FTIR光谱显示，在玻璃网络中掺入V ₂ O ₅有助于转化玻璃的结构单元。 [BO ₃ ]变为[BO ₄ ]。
