Abstract

A method has been developed for separation of ionic and electronic conductivity in mixed conductors. The procedure is accomplished by using blocking electrodes and the Kramers-Kronig relations for separating the dc conductivity from total response. This method was applied to lithium inserted and deinserted sample of Pr0.56 Bi0.04 Li0.2 Ti O3. This material is an ionic conductor, and after insertion, electronic conduction appears in the sample. The deinserted sample has a similar electric behavior to the original material. This method does not need any previous model when processing the data. Hence, it avoids those modeling related mistakes and increases the possibilities of dielectric spectroscopy.
