Abstract:

Glass frits with high B2O3 concentrations, when combined with high-alumina concentration nuclear waste, will form glasses with durabilities that are acceptable for disposal (normalized boron release of <1.7 g/L) and predictable using a free energy of hydration model. Glasses with nepheline discriminator values closest to 0.62 showed significant differences in durability between the quenched and heat-treated versions. Nepheline crystallized in the glass with the lowest nepheline discriminator value. The high-B2O3 frit was successful in producing glasses without crystallization at waste loadings of up to 45 wt%. The melt rate of this frit was also considerably improved (13.1 g/min).
