Solubilities of nickel and cobalt chalcogenides in a nuclear waste glass melt

Description

The solubilities of NiS, NiSe, NiTe, CoS, and CoSe were determined in the reference glass melt SRL-131 (Savannah River Laboratory frit number-sign 131) as a function of the melt temperature and imposed oxygen fugacity. The solubility of each metal chalcogenide was monitored by the concentration of both the cation and the anion in the glass melt equilibrated with an immiscible metal chalcogenide layer. The solubilities of the chalcogenides decrease with decreasing oxygen fugacity. In general, NIS is the least soluble of these compounds in SRL-131. Thus, processing conditions must be adjusted to avoid the formation of NiS during accidental excursions to reducing conditions; alternatively, NiS could be intentionally precipitated from the waste system to concentrate precious metals
