Abstract |
CaCu3Ti4O12 and CaTiO3 nanoparticles with sizes of about 30–90 nm were simultaneously prepared using a chemical combustion method employing glycine as fuel. CaCu3Ti4O12 and CaTiO3 phases without impurity were successfully achieved using a relatively low calcination temperature of 800 °C. Dense microstructure was obtained after sintering for 2 h. The sintered CaCu3Ti4O12/CaTiO3 nanocomposites exhibited a low loss tangent of 0.05 and high dielectric permittivity of 1.01 × 104 at 1 kHz with good temperature stability over the range of −60 to 100 °C. The nonlinear current–voltage properties were also investigated. The dielectric response and nonlinear electrical properties can be well described to be associated with the electrical responses of internal interfaces, i.e., CaCu3Ti4O12–CaTiO3 and CaCu3Ti4O12–CaCu3Ti4O12 interfaces. |
