Dielectric and Piezoelectric Properties of $xPb(Al_{2/3}W_{1/3})O_3-(1-x)Pb(Zr_{0.52}Ti_{0.48})O_3$ Ceramics System

ABSTRACT

Dielectric and piezoelectric porperties of pseudoternary xPb(Al2/3W1/3)O3-(1-x)Pb(Zr0.52Ti0.48)O3 (x=1~10mol%) ceramic system have been investigated as a function of the amount of PAW[Pb(Al2/3W1/3)O3] and sintered from 110$0^{circ}C$ to 120$0^{circ}C$ for 1hr. As the amount of PAW increases, the c/a of tetragonal structure decreases. The grain size was reduced with increasing the amount of PAW addition. However, the density, dielectric constant and electromechanical coupling factor(kp) exhibited a maximum value at the amount of 5mol% PAW addition.
