Waste glass/metal interactions in brines

Technical Report ·
OSTI ID:5879731

Leaching studies of MCC 76-68 glass in synthetic brines high in NaCl were performed from 50 to 150/sup 0/C and included interactive testing with ductile iron and titanium. Hydrolysis of the glass matrix was generally slower in saturated brines than in deionized water, due to a lower solubility of silica in the brines. Inclusion of ductile iron in the tests resulted in accelerated leach rates because irion-silica reactions occurred which reduced the silica saturation fraction. At 150/sup 0/C, iron also accelerated the rate of crystalline reaction product formation which were primarily Fe-bearing sepiolite and talc. 16 references.
