| Abstract Scope |
Over past decades, we have explored the processing and effects of doping on calcium copper titanate (CaCu3Ti4O12 or CCTO) perovskites for dielectric energy storage applications. Although the perovskites are excellent materials with very high dielectric constants for a variety of space components, such as, for energy storage in satellites, the CCTO has low resistivity and is affected by high-energy radiations. The goal is to develop suitable materials for energy storage in space components that have resilience to high-energy radiation. For this reason, we have started working on high atomic number and high-density materials such as doping gallium and thallium in CCTO perovskites. We studied the impact of material processing on resistivity under several conditions. Furthermore, we carried out radiation modeling of these compounds using OLTARIS software tool. In this paper, we discuss the results of material processing and characterization, as well as radiation modeling of these new perovskite materials. |
