dc.description.abstractThe lithium substituted Na2Ti3O7 ceramics with a general formula (Na2-xLixTi3O7) with (x = 0.1) have been synthesized by high temperature solid-state reaction technique. Preliminary EPR analysis and detailed temperature and variable frequency dielectric, conductivity measurements were carried out on the prepared sample. The lithium ions are accommodated with the sodium ions in the interlayer space. The EPR spectrum of Na1.9Li0.1Ti3O7 confirms the partial reduction of Ti4+ ions to Ti3+. The observed dispersion in the dielectric constant-temperature relation can be explained on the basis of Maxwell-Wagner model. The conductivity plots between ln (σT) versus 1000/T have been divided into four regions. The various conduction mechanisms in the different regions have been stressed in this paper. The interlayer ionic conduction seems to play major role in conduction towards higher temperature.en_US
