摘要
摘要:合成了适合于高铁固定的ZrO2掺杂na - ba -硼硅酸盐玻璃，并研究了其在不同水介质中的腐蚀行为。水解稳定性随掺杂量的增加而增加，直至5 mol %;高于此值，玻璃的玻璃化倾向强烈增强。出乎意料的是，ZrO2的掺入降低了1M HCl溶液中的腐蚀稳定性，低ZrO2含量在1M Na2CO3溶液中的耐腐蚀性也较低。对于人工海水，掺杂效应可以忽略不计。30% UO3的加入使玻璃结构得到了显著的稳定。
Chemical Durability of Uranium Oxide Containing Glasses
Abstract ZrO2 doped Na-Ba-borosilicate glasses suitable as matrix materials for HLW immobilization were synthesized and corrosion behaviour was investigated in different aqueous media. Hydrolytic stability is increased with the doping level until 5 mol %; above this value the glass vitrification tendency is strongly intensified. Unexpectedly, ZrO2 doping diminished the corrosion stability in 1M HCl solution, and low ZrO2 content showed a low corrosion resistance in 1M Na2CO3 solution also. Doping effect was negligible in case of synthetic seawater. The glass structure is significantly stabilized by the integration of the 30% UO3 added.
