Non-stoichiometric oxides of La, Sm and Nd have been prepared from solid state decomposition of their carbonates. Electrical conductivity, magnetic susceptibility and catalytic activity have been studied. Samples obtained from carbonates are found to be more reactive than those obtained from nitrates. These oxides show semiconducting behaviour.
