| Abstract: | The influence of rare earth oxide dopants on the relative dielectric constant,thermal stability and dielectric dispersion of BaTiO_3 ceramic capacitance materials wasstudied.Rare earth oxides CeO_2,Sm_2O_3 and Dy_2O_3 were separately added into theBaTiO_3 capacitance materials.The temperature dependence of dielectric constant anddispersion was measured and the influence of the three dopants on the dielectriccharacteristics of the ceramic materials was compared.Some useful results wereobtained. |
