Effect of Bi2O3-B2O3-CuO Additives on Dielectric Properties and Energy Storage of BaTiO3 Ceramics

Article Preview

Abstract:

High density BaTiO3 ceramics have been prepared by the addition of CuO-Bi2O3-B2O3 mixed oxide. The results indicate that the sintering temperature of BaTiO3 bulk can be decreased by about 300°C and high dielectric behavior can be remained. The CuO-Bi2O3-B2O3 additives can increase the breakdown strength, and leads to an obvious enhancement of the energy density, which is nearly 2 times of pure BaTiO3.
