摘要: CaCu 3 Ti 4 O 12 ceramics substituted by Mg for Ca were prepared the solid state reaction method. The crystal structures, microstructures, and dielectric properties of 1- x Cu investigated. At lower doping concentrations, substitution caused a decreased lattice constant, while at higher some dopants started to replace resulted in an increased could also due similar ion radius between ions. was found promote grain growth during sintering. Grain boundary resistance be doping. Enhanced observed with =0.05 frequency range from 1 kHz 20 kHz. For other losses generally lowered.
