The Effects on the Structures and Properties in the Oxide-Ion Conductor
2Mo 2O 9 by Partial Substituting Ba for La. — The oxide-ion conductors
17- 016 La
(La1-xBax)2Mo 2O9-δ (x = 0.02—0.10) are synthesized by solid state reactions of stoichiometric mixtures of La2O3, MoO 3, and BaCO3 (500 °C, 12 h followed by pressing
at 200 MPa and sintering at 950 °C for 10 h). The samples are characterized by XRD,
a.c. impedance spectroscopy, and thermal dilatometry. For the dopant content x = 0.08,
the material exhibits optimal electrical properties and the conductivity reaches a maximum of 0.046 and 0.075 S/cm at 800 and 850 °C, respectively. — (HE*, T.; HUANG,
