Abstract
In this paper, specimens was manufactured in general method annexing PAN-PZT+0.8wt%Mn+1wt% Nb ceramics doped by Sr(0.0 ~ 1.2 wt%). and the following conclusion has been deduced. In XRD, the crystal structure of ceramic has the rombohedral structure and consequently the specimen characterized by MPB was manufactured. According to dopping with Sr, electromechanical factor(kp) little is changed. kp was maximum value 31.31[%] at Sr 1.2[wt%]. mechanical quality factor(Qm) was maximum value 371.879 at Sr 0.6[wt%].
