This paper reports the influences of the post-sintering annealing in argon and uniaxial compressive pre-stress on the giant dielectric properties of the CaCu3Ti4O12 ceramics sintered at 1100 °C in air for 6 and 16h. The CaCu3Ti4O12 ceramic sintered at 1100 °C for 6h exhibited high ε′ of ∼1 × 104 whe...
