ABSTRACT For the direct vitirification of low level radioactive wastes containing metallic aluminum, the oxidation and vitirification of aluminum was carried out using lead borate glass as a flux. Among the six fluxes employed in this study, 0.11Na2O ・3PbO ・B2O3 was the most suitable for the oxidation and vitirification of aluminum based on the initial oxidation rate and alumina solubility. The increase of the lead fraction in the flux increased the oxidation rate, while the sodium fraction affected the alumina solubility resulting in the product maintaining its transparent appearance. The agglomerate product by the oxidation was confirmed metallic lead by X-ray diffraction analysis, and its impurities, aluminum, boron and sodium, were lower than 0.2 wt% by the quantitative analysis.

铝与硼酸铅玻璃的氧化和玻璃化处理低放射性废物

摘要 对于含金属铝的低放射性废物的直接玻璃化，采用硼酸铅玻璃作为熔剂对铝进行氧化和玻璃化。在本研究使用的六种助熔剂中，根据初始氧化速率和氧化铝溶解度，0.11Na2O·3PbO·B2O3 最适合铝的氧化和玻璃化。助焊剂中铅含量的增加增加了氧化速率，而钠含量影响了氧化铝的溶解度，导致产品保持其透明外观。通过X射线衍射分析证实氧化产生的团聚产物为金属铅，其杂质铝、硼和钠通过定量分析低于0.2wt%。
