Abstract

The effect of doping of zinc oxide on the structural and thermal properties of cesium loaded iron phosphate glass has been studied. The composition of glasses prepared for the present study is xZnO–20Cs₂O–(32–0.4x) Fe₂O₃–(48–0.6x) P₂O₅ with x = 0–15 (mol%) wherein Fe/P ratio remains 0.67. Glasses were synthesized using conventional melt quenching technique and were characterized by XRD, DTA, Raman and FTIR spectroscopy. All the glasses showed X-ray amorphous except x = 15 mol% ZnO. Chemical durability of the glasses was studied by PCT-B. The addition of cesium in pristine IPG decreased the thermal stability. Doping of 2.5 mol% ZnO marginally increased the thermal stability and chemical durability compared to 20 mol% Cs loaded IPG. Further addition of ZnO in cesium loaded IPG resulted in slow depolymerization of pyrophosphate network. All the glasses exhibited a low Cs leach rate in the order of 10^–6 g/cm².day.

掺锌磷酸铯铁玻璃的合成与性能研究

研究了氧化锌掺杂对磷酸铁铯玻璃的结构和热性能的影响。本研究制备的玻璃成分为 xZnO-20Cs2O-(32-0.4x) Fe2O3-(48-0.6x) P2O5，其中 x = 0-15（mol%），Fe/P 比值为 0.67。玻璃采用传统的熔体淬火技术合成，并通过 XRD、DTA、拉曼和傅立叶变换红外光谱进行表征。除 x = 15 mol% ZnO 外，所有玻璃都呈现 X 射线无定形。通过 PCT-B 研究了玻璃的化学耐久性。在原始 IPG 中添加铯会降低热稳定性。与铯含量为 20 摩尔% 的 IPG 相比，掺杂 2.5 摩尔% ZnO 稍微提高了热稳定性和化学耐久性。在铯负载 IPG 中进一步添加氧化锌会导致焦磷酸网络缓慢解聚。所有玻璃的铯浸出率都很低，约为 10-6 g/cm2.天。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
