Abstract

Pourbaix diagrams (electrode potential-pH diagrams) for Ti-Br^--H₂O system at 25°C in the absence and presence of titanium hydrides were developed in 400, 700, 850, and 992g/L LiBr solutions. The diagrams were compared with the simple Ti-H₂O system at 25°C. Comparison of the simple Ti-H₂O system with the diagrams of the Ti-Br^--H₂O system at 25°C showed that the titanium solubility range in the acid, neutral, and weak alkaline areas of the diagrams extended slightly to both higher pH values and potentials with increasing bromide ion activity and decreasing water activity.
