摘要：

Solubilities of 12 bivalent metal oxides in the molten eutectic mixture CsCl-KCl-NaCl (0.455 : 0.30 : 0.245) at 600-degrees-C have been determined by a potentiometric titration technique using a membrane oxygen electrode Pt(O2)\ZrO2. Solubility products for these oxides and dissociation constants for four oxides have been calculated. Some correlations of solubility with physical constants have been found. Solubilities of oxides studied have been found to be lower than those in the equimolar mixture KCl-NaCl at 700-degrees-C.
