A flux which will mix with ICPP high-level calcined zirconia waste to form a low-viscosity leach-resistant glass at 1100/sup 0/C was developed. Effects of each of the glass additives Na/sub 2/O, B/sub 2/O/sub 3/, Li/sub 2/O, ZnO, CuO, and P/sub 2/O/sub 5/ are compared on the basis of leach resistance and viscosity. Methods to analyze fluoride content were developed. A glass forming flux containing 2% CuO, 24% Na/sub 2/O, 8% B/sub 2/O/sub 3/, and 66% SiO/sub 2/ was chosen for its ability to produce a highly leach-resistant (0.20 wt % lost at pH 3.7 and 25/sup 0/C after 19 hours) waste glass and its ability to accept a wide range of waste loadings (25 to 40 wt % calcine in the final glass).
