Solubility equilibrium of silver(I) oxide in molten lithium nitrate + potassium nitrate mixtures
Abstract
The solubility equilibrium of silver oxide has been investigated in molten mixtures of LiNO3+ KNO3, in the presence of water at controlled activity. The ranges of temperature and molar composition of the solvent mixtures were, respectively, 415–525 K and 30–59 mol % LiNO3.
The dependence of the solubility of silver oxide on the composition of the solvent mixture has been interpreted on the basis of a recently developed quasi-lattice model for the dissolution processes of sparingly soluble ionic compounds in ionic melts.
