摘要: 本文主要针对高放废液中贵金属(PGMs)的含量、存在形态,玻璃固化体中PGMs的溶解度、存在形态、颗粒大小等化学行为进行归纳,同时针对玻璃固化过程中PGMs对玻璃性质(流变、粘度、热导、电阻)的影响进行总结。该文为研究典型贵金属元素在玻璃中的溶解度及其变化规律、典型贵金属元素在玻璃中的化学行为及沉淀机理以及典型贵金属元素对玻璃性质的影响研究提供调研基础,可为我国玻璃固化技术的研发提供前期的理论依据。

Abstract: This paper mainly summarized the chemical behaviors (the content and the existing form) of precious metals (PGMs) in high-level liquid radioactive waste (HLLW) and the solubility, the existing form and the granularity of PGMs in HLLW glass. At the same time, the influence of PGMs on the properties of HLLW glass (rheology, viscosity, thermal conductivity and resistance) was summarized. The results were expected to provide a research basis for the solubility, the chemical behavior and sediment mechanism of typical PGMs in HLLW glass. Besides, The results were hopeful to provide a theoretical basis for studying the influence of typical PGMs on the properties of HLLW glass.

Key words: precious metal, high-level liquid radioactive waste, vitrification, solubility, properties of glass
