Abstract

Transport number measurements and impedance spectroscopy in controlled temperature and atmosphere were used to investigate the electrical properties of La₂Mo₂O₉ sintered samples. These samples were prepared from nanocrystalline La₂Mo₂O₉ powders as obtained from a new soft chemistry route involving the polymerisation of acrylamide. By means of the electromotive force method measurements, the sintered compound was found mainly oxygen conductor in the range of 400°C-800°C with oxide-ion transport number greater than 0.99. The effect of the oxygen partial pressure on the electrical conductivity of La ₂Mo₂O₉ was investigated by impedance spectroscopy from 1 to 10^-22 atm, showing a highly stable conduction properties up to 10^-17 atm at 800°C.
