对于239 Pu含量较高且很难回收利用的含Pu废物,在安全处置前须进行妥善的固化处理。玻璃和玻璃陶瓷因在制备方面具有较陶瓷简单的工艺、低廉的成本和高效的产出被认为是目前处理含Pu废物综合优势明显的固化基材,因而得到了广泛和深入的研究。本文对碱硼硅酸盐玻璃、镧硼硅酸盐玻璃、铁磷酸盐玻璃以及含钙钛锆石、烧绿石或独居石结晶相的玻璃陶瓷等在含Pu废物固化方面的研究进展进行了综述,包括其组分、Pu包容量和化学稳定性,并进行了对比分析,认为在对玻璃固化基材继续研究与应用的基础上,玻璃陶瓷有望成为固化绝大多数含Pu废物的较佳选择。
對于239 Pu含量較高且很難迴收利用的含Pu廢物,在安全處置前鬚進行妥善的固化處理。玻璃和玻璃陶瓷因在製備方麵具有較陶瓷簡單的工藝、低廉的成本和高效的產齣被認為是目前處理含Pu廢物綜閤優勢明顯的固化基材,因而得到瞭廣汎和深入的研究。本文對堿硼硅痠鹽玻璃、鑭硼硅痠鹽玻璃、鐵燐痠鹽玻璃以及含鈣鈦鋯石、燒綠石或獨居石結晶相的玻璃陶瓷等在含Pu廢物固化方麵的研究進展進行瞭綜述,包括其組分、Pu包容量和化學穩定性,併進行瞭對比分析,認為在對玻璃固化基材繼續研究與應用的基礎上,玻璃陶瓷有望成為固化絕大多數含Pu廢物的較佳選擇。

Plutonium‐containing waste with characteristics of high 239 Pu content and difficult reuse must be immobilized as soon as possible before safe disposal .Glass and glass‐ceramics considered to be more excellent confinement matrices (simpler process , lower cost and higher productivity ) for immobilizing plutonium‐containing waste than ceramics were studied extensively and thoroughly including alkali borosilicate glass , lanthanide borosilicate glass ,iron phosphate glass and zirconolite ,pyrochlore or mona‐zite‐based glass‐ceramics .T heir chemical composition ,chemical durability and the con‐tent of plutonium or its surrogate were presented and discussed by contrast in this paper .It is believed that glass‐ceramics will be a good alternative for immobilizing most of plutonium‐containing waste through consistently investigating and applying .
