摘　　要：采用熔融冷却法制备中硼硅医药玻璃,以ZrO_2等质量替代Al_2O_3。通过红外光谱分析玻璃结构,测试玻璃密度、热膨胀系数、高温粘度以及化学稳定性。研究结果表明:随着ZrO_2替代Al_2O_3质量增加,玻璃结构中[BO_3]增多,[BO_4]减少,密度逐渐增加,玻璃的热膨胀系数先增大后减小;高温粘度呈现先降低后增大趋势,ZrO_2增加对玻璃颗粒耐水和耐酸性能影响不大,而对玻璃颗粒耐碱性能有显著提升作用。Pharmaceutically medium borosilicate glass were prepared by using melt cooling method, which replaced aluminum oxide with equal quantity of zirconium oxide. The structure of glass was analyzed by infrared spectroscopy. The density, coefficient of thermal expansion,high-temperature viscosity and chemical stability were also tested. The experiment results shows that with the content of zirconium oxide increasing,the quantities of [ BO3 ] increase, the numbers of [ BO4 ] decrease. And the density gradually increases. The coefficient of thermal expansion and high-temperature viscosity both increase firstly and then reduce. When the zirconium oxide added, it has little effect on water and acid resistance, but the alkali-resistance improves significantly.
