Abstract

For glass systems related to two potential nuclear-wasteglasses, ABS–39 and ABS–41, the 600°C isotherm of the metastable immiscibility field has been located experimentally. Both glasses are in the one phase glass field down to temperatures below 600°C. ABS–39 and ABS–41 are Na2O-B2O3-SiO2 glasses containing 1.66 wt% UO2 and 9 wt% of simulated fission products. Additional components in ABS–39 are Al2O3 and Fe2O3. In ABS–41 these two oxides are partly substituted with ZnO and Li2O. This substitution causes an extension of the metastable immiscibility field relative to the ABS–39 system.
