Descripción
Thermogravimetric analysis (TGA) technique in controlled oxygen partial pressure (pO 2) atmospheres has been used to obtain equilibrium oxygen content data as a function of pO 2 on the La 2Mo 2O 9-δ system resulting from the partial reduction of fast oxide-ion conductor La 2Mo 2O 9 (LM). Thermodynamic conditions for stabilization of crystalline La 7Mo 7O 30 and amorphous La 2Mo 2O 7-y at 718 °C have been determined and discussed. At 608 °C, the compound reported for the first time La 2Mo 2O 8.96 (LM896) has been found. The crystalline form and transition temperature in LM896 have been identified by X-ray diffraction at room temperature (XRD) and at controlled temperature. Conductivity curves obtained by electrochemical impedance spectroscopy (EIS) as a function of temperature for both LM and LM896 have been compared. The results indicate that LM896 is a mixed ionic and electronic conductor (MIEC). © 2012 The Royal Society of Chemistry.
