프레스 압력 변화에 따른 PZT 후막의 전기적 특성

The electric properties of PZT thick film by pressure variation

$Pb(Zr_{0.4},Ti_{0.6})O3$, $Pb(Zr_{0.6},Ti_{0.4})O_3$ powder were prepared by the sol-gel method using a solution of Pb-acetate, Zr n-propoxide and Ti iso-propoxide. PZT thick film were fabricated by the screen printing method, and the structural and ferroelectric properties asafunting of the sintering temperature were studied. PZT film thickness, obtained by four screen printing, was approximately $100{\sim}120{\mu}m$. The relative dielectric constant and the dielectric loss of the PZT thick film sintered at $1050^{\circ}C$ were approximately 676 and 1.4%, respectively.
