    • Abstract

       

      The temperature dependence of DC electrical conductivityσ of sodium acetylacetonate compound Na(ac,ac) is studied for fresh and polarized samples. Both samples show semiconductor behaviour, but the value ofσ for the fresh sample is higher than that of the polarized sample. Three distinct regions are observed in the temperature conductivity curves. The conduction mechanism of each region is discussed. Anomalous conductivity phenomena are observed above 105°C and attributed to unidirectional intermolecular or phase transformation. The results are discussed on the basis of ionic conduction and some conduction parameters such as conduction energyEc, transport energyEu, ion mobilityu, free ion densityn, are calculated.
