Admittance of polycrystalline sodium niobate synthetized with nonstoichiometric proportion of the constituent oxides has been investigated at elevated temperatures. Basic values characterizing the AFE-PE phase transformation have been determined. Effect of sodium oxide excess on the phase transformation has been defined and shortly discussed.
