| Abstract: BaTiO3 ceramics doped with Nd2O3(the additive content was respectively 0.001,0.002,0.003,0.005,0.01,0.03mol)were prepared by Sol-Gel method. Effects of Nd2O3 contents on the dielectric constant (ε), the dielectric loss (tanδ) ,the Curie-temperature (TC) and the resistivity (ρ) of BaTiO3 ceramic were studied. When Nd2O3 content was 0.001mol and 0.002mol, the dielectric constant was increased obviously, but the dielectric loss was also increased. When Nd2O3 content was 0.003mol, the dielectric constant was increased, and the dielectric loss was decreased, which was suitable for application in condenser. The resistivity was decreased obviously with the increasing of Nd2O3 contents, the resistivity was the smallest when Nd2O3 content was 0.001mol. The Curie-temperature was also decreased with the increasing of Nd2O3 contents. |
