Abstract
AbstractThermodynamic assessment of electrochemical reduction of TiO2 to Ti metal in CaCl2 molten salt electrolyte is discussed. The conversion of TiO2 to Ti takes place via multi-step reduction process that involves formation of several intermediates or sub-oxides of titanium at different reaction conditions. A complete understanding of these redox chemical reactions, and change in reaction Gibbs energy is very essential for efficient extraction of the Ti metal. This research article discusses the thermodynamic modelling studies on the formation of different titanium sub-oxides and corresponding reaction conditions (change in Gibb’s energy, temperature, and pressure) during TiO2 reduction to Ti metal.
