摘　　要：高放废液中的Mo在玻璃中的溶解度较低,在高放废液的玻璃固化中易形成黄相,黄相的出现对玻璃固化过程和固化体性能均不利,限制了玻璃固化体中废物的包容量。通过改变玻璃配方或开发研究新的配方提高固化体中Mo含量,可以消除黄相。本文综述了近年来国内外针对玻璃固化过程中Mo的化学行为研究所取得的研究进展。The presence of significant amounts of molybdenum in high level waste(HLW)streams can lead to the formation of a molybdate salt phase(“yellow phase”)during vitrification.These salts are undesirable from both melter operations and product quality perspectives,such that yellow phase formation can become the primary factor that limits waste loading in the HLW glass product.Improvement of Mo content and elimination of yellow phase in glass by changing glass formulation or developing new formulation are feasible.In this paper,the research progress of the chemical behavior of Mo during vitrification is reviewed.
