摘要
硼硅酸盐玻璃具有包容率高、熔制温度合理、对废液组分变化适应性强、抗辐射、化学稳定性好等优点,是目前工业应用最广泛的高放废液固化玻璃基质。本文综述了硼硅酸盐玻璃固化高放射性元素的机理、高放废液硼硅酸盐玻璃固化体的关键产品性能、工艺性能和经济性指标的相关研究进展,以及硼硅酸盐玻璃固化体的工程化应用情况。根据国内硼硅酸盐玻璃固化体的研究现状,未来仍需开展系统的硼硅酸盐玻璃配方研究,建立配方设计模型以适应不同类型高放废液的固化需求;同时需开展玻璃固化体的腐蚀机理研究和长期化学稳定性评估,以制定并完善玻璃固化体评估标准。
Borosilicate glass is currently one of the most widely used matrix materials for high-level liquid waste vitrification due to its advantages of high waste loading,suitable melting temperature,strong adaptability to changes in waste components,radiation resistance and good chemical durability.This review represented recent work on the high-level waste vitrification mechanism of borosilicate glass,key product performance,process performance and economic indicators of borosilicate glass matrix of high-level liquid waste,as well as their engineering applications.This review suggested to carry out the systematic borosilicate glass formulation research in the future and establish the glass formulation design models to meet the vitrification requirements of different types of high-level waste liquids.In addition,the leaching mechanisms and long-term behaviors of borosilicate glass matrix could be also carried out to improve the evaluation criteria for waste glasses.
