Abstract

In this paper, the structural, dielectrial and piezoelectrical properties of 0.03Pb(Sb$\sub$1/2/Ti$\sub$0.495/)O$_3$+Xwt% MnO(x= 0, 0.3, 0.4, 0.5, 0.7) system ceramics were investigated as a function of the addition of MnO. As a result, the samples of 0.3wt% MnO content showed the highest mechanical quality factor(Qm) of 1487, and its dielectric constant and electro mechanical coupling factor(Kp) 1357, 54.3%, respectively. Therefore, the dielectrial and piezoelectrical properties of the composition ceramics were indicated as the materials suitable for piezoelectric transformer.
