摘要
研究了铁磷酸盐玻璃固化我国高放废液全分离流程中产出的锶废物及铯废物 ,熔制了相应的固化体。用XRD ,IR测试了固化体的微观结构 ,用产品一致性试验方法 (PCT)研究固化体的化学稳定性。研究表明 :在所选的废物包容量范围内可熔制得均质模拟废物铁磷酸盐玻璃固化体 ,玻璃的主要结构基团为P2 O4 -7。
The iron phosphate glass matrix is recommended for strontium and cesium waste produced by partitioning process of Chinese HLW.The formula of iron-phosphate glasses was designed.Their structure was studied with IR spectra and their chemical durability was measured by the Product Consistency Test(PCT)method.The experimental results show that the glass matrix has good chemical durability within experimental formulas.The main group of the iron-phosphate glasses is P 2O 4- 7.When the ratio of O/P is 3.5 in the formula,the glass matrix has the best chemical durability.
