Abstract:
1. A method of preparing an energy storage component with high dielectric permittivity wherein the method includes the steps of: a) mixing a stoichiometric amount of elements and obtaining a mixture; b) drying the mixture from step (a) to obtain dried powder; c) grinding the dried powder and calcining the ground dried powder; d) obtaining calcined dried powder; e) pressing the calcined dried powder into a plurality of first pellets; f) firing the first pellets from step (e) to form a fired product; g) repeating steps (c to f) at least twice using said fired product instead of said dried powder; h) sieving of a product resulting from step g); i) pressing the sieved product to obtain a plurality of uniform pellets; j) sintering the plurality of uniform pellets.
