摘要：

Pourbaix diagrams (electrode potential-pH diagrams) for Ti-Br--H2O system at 25 degrees C in the absence and presence of titanium hydrides were developed in 400, 700, 850, and 992 g/L LiBr solutions. The diagrams were compared with the simple Ti-H2O system at 25 degrees C. Comparison of the simple Ti-H2O system with the diagrams of the Ti-Br--H2O system at 25 degrees 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.
