Lamb, K. M.; Cole, H. S.

Simulated high-level ICPP zirconia waste calcine is pelletized on a 41-cm-diam pelletizer using 5% bentonite, 2% metakaolin, and 2% boric acid for solids binders and 7M phosphoric and 4M nitric acid as the liquid binders. After heat treatment at 800/sup 0/C for 2 hours, the pellets are impact resistant and have a leach resistance of 10/sup -4/ g/cm/sup 2//day, based on Soxhlet leaching for 100 h at 95/sup 0/C with distilled water.
