Popis: | CaCu3Ti4O12 (CCTO) ceramic was synthesized by conventional solid-state reaction technique and sintered at 1353K for 10 hours. The dielectric properties of CCTO were analyzed in 1Hz-5 MHz frequency range, from room temperature to 413K. The ferroelectric properties of CCTO were analyzed at various frequencies viz. 50 Hz, 100 Hz and 200 Hz at temperatures (298K to 413K). Result of these investigation points that with increasing temperature the values of coercive field (Ec) and remnant polarization (Pr) decrease while maximum polarization (Pmax) increases non-linearly. P-E hysteresis loop of CCTO goes to slimed and a ferroelectric to Para-electric phase transition is observed at 403K. |
