Fixation of Hanford sludge by conversion to glass

Conference ·
OSTI ID:7305411
Redox and Purex process sludges stored at Hanford can be converted to durable borosilicate glasses by melting at 1100--1400/sup 0/C charges containing 30 to 40 weight percent washed, dried sludge, 45 to 60 weight percent SiO/sub 2/, 5 to 15 weight percent B/sub 2/O/sub 3/, 0 to 10 weight percent Na/sub 2/O, 0 to 5 weight percent Li/sub 2/O, and 0 to 5 weight percent TiO/sub 2/. Leach rates in deionized water (25/sup 0/C) for the glasses range from about 10/sup -7/ to 10/sup -5/ g/cm/sup 2/-day.
