Electrical behavior of CaO-doped ThO sub(2)
The total a.c. conductivity of a Ca sub(x)Th sub(1-x)O sub(2-x) solid solution with fluorite-type structure was measured at 1360 Hz with 0 less than or equal to x less than or equal to 0.25 and at temperatures of 100 to 600 degree C. The complex impedance behavior was investigated at frequencies of...

| Summary: | The total a.c. conductivity of a Ca sub(x)Th sub(1-x)O sub(2-x) solid solution with fluorite-type structure was measured at 1360 Hz with 0 less than or equal to x less than or equal to 0.25 and at temperatures of 100 to 600 degree C. The complex impedance behavior was investigated at frequencies of 10 to 10 super(5) Hz and temperature of 300 to 500 degree C. 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 greater than or equal to 0.03. |
