초록

In consideration of piezoelectric characteristic and Temperature stability, 3-element system dopped with NiO, $Cr_2O_3$ well-known as Hardner and Stabilizer whose primary element is PZT was eximanated its structure, piezoelectric characteristics, dopping with Nio, $Cr_2O_3$. We think that piezoelectric Characteristic is developed, remenent polarization and $E_c$ can developed in specimens by dopping with NiO, $Cr_2O_3$ additive. also, electromechanical quality factor largely showed tendency of decrement. According to dopping NiO, $Cr_2O_3$ more.
