The thermodynamic properties of Fe_(2)Ti_(3)O_(9) and Fe_(2)TiO_(5) were measured by means of the following solid state electrolyte cells:Pt,Fe+"FeO"||ZrO_(2)(CaO)||FeTiO_(3)+Fe_(2)Ti_(3)O_(9)+Fe_(2)O_(3),Pt... The thermodynamic properties of Fe_(2)Ti_(3)O_(9) and Fe_(2)TiO_(5) were measured by means of the following solid state electrolyte cells:Pt,Fe+"FeO"||ZrO_(2)(CaO)||FeTiO_(3)+Fe_(2)Ti_(3)O_(9)+Fe_(2)O_(3),Pt Pt,Fe+"FeOM"||ZrO_(2)(CaO)||FeTiO_(3)+Fe_(2)TiO_(5)+TiO_(2),Pt From the experimental data,the Gibbs energies of formation of Fe_(2)Ti_(3)O_(9) and Fe_(2)TiO_(5) were obtained:△G^(0)_(pr)(kJ·mol^(-1))=3459.7-0.847T,(1053K<T<1153K) △G^(0)_(pb)(kJ·mol^(-1))=-1700.2-0.465T,(1173K<T<1273K) Experimental results fit approximately to those of estimation. 展开更多
