Abstract

In this study, the structural, dielectric and piezielectric properities of $xPb(Mg_{1/3}Nb_{2/3})O_3-(0.5-x)Pb(Ni_{1/3}Nb_{2/3})O_3-0.5Pb(Zr_{0.3}Ti_{0.7})O_3$ ceramics were investigated with the substitution of $PbMg_{1/3}Nb_{2/3}O_3$. The results showed that the substitution of the $PbMg_{1/3}Nb_{2/3}O_3$ was effective in increasing the dielectric constant and electromechanical coupling factor $(K_p)$. The dielectric constant, dielectric loss and Kp showed the highest values of 4293, 2.4%, 0.59 relatively, when the substitution of amount of $PbMg_{1/3}Nb_{2/3}O_3$ was 5 mol%.
