Abstract

A series of compounds, La2/3-xLi3xMoO4 were prepared. Their structures are tetragonal scheelites with the cationic defects. The cell parameters a, c and values of c/a decrease with the increasing of the substitution amount (3x) of lithium ion. Cationic vacancies are getting more as Li+ concentration is lower. The diffusion of lithium ion is predominant. The concentration of charge carriers increases with the increase of the substitution amount (3x) of lithium ion, meanwhile, the concentration of cationic vacancies decreases. The conductivity approaches the best when the substitution amount (3x) of lithium ion is about 0.3. The conductivity of La0.567Li0.3MoO4 is 6.5×10-6 S · cm-1 at room temperature.
