| Abstract Scope |
The objective of this study is to develop high dielectric low loss material for energy storage using large density and high Z atoms to reduce the radiation effects on the performance. The calcium copper titanate (CaCu3Ti4O12 or CCTO) has been well studied as a potential candidate for high dielectric capacitor material. These materials belong to body centered cubic structure with a slight tilt of (TiO6)-4 octahedrons facing each other. Experiments have shown that dielectric constant was very much dependent on the processing and starting components. To achieve the objectives, we have developed gallium-based material system Ga2/3 Cu3Ti4O12 (GCTO) and Pr2/3Cu3Ti4O12 (PCTO) to evaluate the difference due to valency, ion size and density on the resistivity and dielectric constant in the range of 100Hz to 100 KHz frequency at bias voltage of 50 mV to 1000mV. Significant difference in dielectric and resistivity were observed. |
