摘要/Abstract

摘要： 以硼硅酸盐玻璃作为基础玻璃基材,通过熔融法制备了含16%(质量分数)模拟高放废液的玻璃固化体,探究了碱土金属氧化物含量对玻璃固化体析晶行为的影响,以期在保证玻璃固化体性能要求的前提下,通过控制碱土金属氧化物的含量抑制玻璃固化体的析晶倾向。结果显示:碱土金属氧化物(CaO+MgO+BaO)含量在7%~19%(质量分数)时,玻璃固化体析晶上限温度和析晶率随碱土金属氧化物含量的降低而逐渐降低;玻璃网络聚合度的增加能够显著增强玻璃固化体的抗析晶性能,当碱土金属氧化物含量低于11%(质量分数)时玻璃固化体中硫酸盐的溶解度明显下降。基于包容0.7%(质量分数)SO₃的要求,碱土金属氧化物含量适宜组成应控制在11%(质量分数)以上。

Abstract: Borosilicate glass was treated as basic glass substrate, and the influence of alkaline earth metal oxide content on the crystallization behavior of waste glass containing 16% (mass fraction) simulated high level liquid wastes was investigated, in order to suppress the crystallization tendency by controlling the content of alkaline earth metal oxide under the premise of ensuring the performance requirements. The results show that,when the content of alkaline earth metal oxide is 7%~19% (mass fraction), the maximum crystallization temperature and the crystallinity of the waste glass gradually decrease with the decrease of alkaline earth metal oxide (CaO+MgO+BaO) content. The increase of the degree of polymerization of the glass network is beneficial to improving the anti-crystallization performance of the waste glass. However, when the alkaline earth metal oxide content is lower than 11% (mass fraction), the solubility of sulfate has a significant decrease. Based on the requirement of inclusion of 0.7% (mass fraction) SO₃, the appropriate composition of alkaline earth metal oxide content is above 11% (mass fraction).
