The vitrification using borosilicate glass system for rare earth waste, including Y, La, Ce, Pr, Nd, Sm, Eu, Gd, etc, is studied. The optimized glass exhibited viscosity of 7.2 poise and an electrical conductivity of 1.13 S/cm at a melting temperature 1200^oC so that operating variables within the CCIM were evaluated to be very favorable.
