INVESTIGATION OF THERMODYNAMIC PROPERTIES OF THE TI-H SYSTEM USING MOLTEN-SALT ELECTROLYTES CONTAINING HYDRIDE IONS

[摘要] A novel molten salt technique using alkali halide electrolytes, which contain hydride ions, was used to study thermodynamic properties of the Ti-H system at intermediate temperatures (300-415-degrees-C). This electrochemical technique offers a simple, fast, precise and sensitive method for investigation of metal-hydrogen interactions with minimal surface interference at temperatures where no suitable electrolyte was available previously. We report results that extend to a lower hydrogen activity range than any previous studies. The results agree with those measured by others using conventional gas-volumetric or calorimetric techniques.
