Résumé     
Gadolinium-doped ceria (known as CGO or GDC) is a good oxide-ion conductor which presents potential application for solid-state electrochemical devices. However, one of the main drawbacks of this material is the high sintering temperature required to obtain dense ceramic. In this paper, we report a new way to reduce densification temperature of CGO by adding x weight percent of La2Mo2O9 material (0 {<}= x {<}= 10). This latter is also a good oxide-ion conductor at high temperature ({>} 580 degrees C) which allows the preservation of the electrochemical properties of CGO as shown by impedance spectroscopy. The sintering behavior is then studied using dilatometric measurements and mechanism of densification is discussed.
