- Abstract
A new kind of high-entropy perovskite oxides (Ce,K)x[(Bi,Na)BaSrCa]1−xTiO3 (x-CKBNBSCTO) were synthesized by using a traditional solid-state reaction method and the dependence of the properties of samples on the content x was also explored. Microstructure analyses found that the most homogeneous particles were obtained when x reached 0.2. The highest dielectric properties can be detected when each element is equal, and the highest dielectric constant and the lowest dielectric loss are captured with the values of 535 and 0.04, respectively. Also, the energy storage is explored, showing a high energy storage efficiency of 85% when x is 0.08.
