Waste glass using a borosilicate frit and simulated zirconia calcine produced at the Idaho Chemical Processing Plant was characterized. Tests included: Soxhlet, acid, and static distilled water leaches, and relative viscosity and crystallinity measurements on both air-quenched and annealed samples. The frit was evaluated to vitrify 10 to 40 wt% calcine. The effects of CaF/sub 2/ content on glass viscosity and crystallinity were measured. Changes in viscosity and leach rate caused by other calcines, partially substituted for the zirconia calcine in the glass, were determined. Varying the Na/sub 2/O to Li/sub 2/O ratio was studied on four modifications of the base glass. Viscosity and leach rates of glasses modified as described above were not significantly altered, but crystalline content of heat-treated glasses significantly increased with increasing CaF/sub 2/ content. 10 figures, 11 tables.
