The solid state reaction mechanism between Li₂CO₃ and TiO₂ forming Li₂TiO₃ has been studied by XRD. The relationship between reaction rate and temperature and the dependence of the reactant fraction (a) on the heating time were investigated. The activation energy of the reaction has been calculated to be 166.2 kJ/mol. The reaction mechanism conformed to the Ginstling-Brounstein model. It is proposed that Li⁺ ions diffuse into TiO₂ particles during the reaction.
