    摘要
  • 摘要: 研究了鈦酸鍶（SrTiO3a）固化體浸出性能的影響因素.采用MCC-1浸出法,分析了鈦酸鍶的浸出率.實驗結果表明：SrTiO3a中各種元素的浸出率隨時間延長而減小,且都小于0.1g·m-2·d-1,比玻璃固化體浸出率要低2～3個數量級;鈦酸鍶的化學穩定性好,是比較好的高放廢物固化體.

     

    Abstract: This paper investigated the influencing factors on the leakage behavior of strontium titanate form SrTiO3a. The leaching rate was evaluated by the materials characterization center method. Experimental results showed that the leaching rate of SrTiO3a gradually decreased with time and was less than 0.1 g·m-2·d-1, twice orders less than that of glass solid. It was found that SrTiO3a had a steady chemical property and was a good form for high lever radioactive-wastes.
