Abstract
The dc electrical conductivity and thermally stimulated discharge
current (TSDC) studies have been made on pure and modified β-eucryptite with
TiO2, Fe2O3 and CuO in the temperature range 303 – 423 K . The calculated
values of activation energy and ionic transference number from dc electrical
conduction indicate the presence of ionic character in the investigated samples.
The global TSDC spectra studies point to a superposition of dipole orientation
and space charge effects. With the aid of the thermal sampling technique, the
complex spectrum could be resolved into its elementary processes. The
compensation effects is observed to be valid and the values of the compensation
temperature and time are found to be 356 K and 1.18 sec respectively.
