Thermodynamic Investigation of Ti-H System by Molten Salt Electrochemical Technique

We have investigated the thermodynamic properties of the Ti-H system including the high-concentration region by utilizing the electrochemical reaction of the hydride ion, in a molten LiCl-KCl-LiH system. Electrode potential-composition isotherms in three single phases, α, β, and δ, and in two coexisting phases, and have been measured at 673-773 K. The relative partial molar quantities of absorbed hydrogen, and and integral quantities, and were estimated. It was confirmed that the obtained results were in good agreement with the reported values derived by using other techniques.
