Abstract: The thermodynamic properties of Fe₂Ti₃0₉ and Fe₂TiO₅ were measured by means of the following solid state electrolyte cells: Pt，Fe+“Fe0”‖ZrO₂ (CaO)‖FeTiO₃+Fe₂Ti₃O₉+Fe₂O₃，Pt Pt, Fe+“Fe0”‖ZrO₂(CaO)‖FeTiO₃+Fe₂TiO₅+TiO₂，Pt From the experimental data，the Gibbs energies of formation of Fe₂Ti₃O₉ and Fe₂TiO₅ were obtained: △G⁰_pr (kJ .mol^-1)= -3459.7-0.847T，(1053 K＜T＜l153K) △G⁰_pb (kJ .mol^-1) =-1700.2-0.465T，(1173K＜T＜1273K) Experimental results fit approximately to those of estimation.
