Metal oxide solubility behavior in high temperature aqueous solutions
Conference

OSTI ID:5405126
The solubility behavior of metal oxides in sub- and super-critical aqueous solutions is quantified using thermodynamic concepts. Three physicochemical phenomena are discussed: (1) metal oxide solid phase stability, (2) metal oxide dissolution reaction equilibria and (3) metal ion hydrocomplex formation. Thermochemical properties of metal oxides/ions representative of the most common constituents of construction metal alloys, i.e., elements having atomic numbers between 22 (Ti) and 30 (Zn), are summarized on the basis of metal oxide solubility studies. 41 refs., 4 tabs., 3 figs.
