Abstract Glasses composed of ternary components (35 – x)Sb2O3–xBi2O3–65P2O5 (0 ⩽ x ⩽ 20 mol%) have been prepared and investigated as a potential alternative to lead-free glass for low temperature applications. Their structural properties were studied by Infrared Spectroscopy IR and Differential Thermal Analysis DTA. Results from the IR showed that Sb3+ and Bi3+ were responsible for glass network structure, which was supported by the diversification of density ρ and molar volume Vm with an increasing amount of Bi2O3. Glass transition temperature Tg, thermal stability, and coefficient of thermal expansion increased after substitution of Bi2O3 for Sb2O3 within the range of 0 mol% to 20 mol%. The water durability decreased and then increased; it could be attributed to the corrosion resistant P–O–Sb bonds. A typical sample of 25Sb2O3–10Bi2O3–65P2O5 possesses excellent properties and can be a promising candidate for further applications.

用于无铅玻璃应用的三元 (35 – x)Sb2O3–xBi2O3–65P2O5 玻璃的制备

摘要 由三元组分 (35 – x)Sb2O3–xBi2O3–65P2O5 (0 ⩽ x ⩽ 20 mol%) 组成的玻璃已被制备和研究作为低温应用无铅玻璃的潜在替代品。通过红外光谱 IR 和差热分析 DTA 研究了它们的结构特性。IR 的结果表明 Sb3+ 和 Bi3+ 是玻璃网络结构的原因，这得到了密度 ρ 和摩尔体积 Vm 随着 Bi2O3 量增加的多样化的支持。在 0 mol% 到 20 mol% 的范围内用 Bi2O3 代替 Sb2O3 后，玻璃化转变温度 Tg、热稳定性和热膨胀系数增加。耐水性先下降后上升；这可能归因于耐腐蚀的 P-O-Sb 键。
