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.
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.
