Abstract

Zn(NbO3)2 doped Sr0.98Ca0.02TiO3 (SCT-xZN) paraelectric ceramics have been obtained by the traditional electroceramic processing. Phase structures and doping effects were investigated by using XRD and Raman. Surface morphology was observed by SEM to evaluate grain growth. The P-E curves were measured and employed to calculate the energy storage density and efficiency. The doping effects on dielectric properties such as permittivity, dielectric loss and breakdown strength were also measured and discussed.
