Description
The total a.c. conductivity of a CaxTh1-xO2-x solid solution with fluorite-type structure was measured at 1360 Hz with O ≤ x ≤ 0.25 and at temperatures of 100 to 6000C. The complex impedance behaviour was investigated at frequencies of 10 to 105 Hz and temperatures of 300 to 5000C. The complex dielectric permittivity was calculated at this frequency and in that temperature range. The activation energy for the bulk conductivity was calculated. Its value is about 1.48 eV for x < 0.03 and about 1.25 for x ≥ 0.03. (author)
