초록

In this paper, we manufactured Pb($Ni_{1/2}$ $W_{1/2}$)$O_3$-Pb($Mn_{1/3}$$Nb_{2/3}$)$O_3$-Pb($Zr_3$Ti)$O_3$ceramics with variation of milling time and investigated its dielectric and piezoelectric properties. Density was increased with the increase of milling time because the sinterability of specimens were improved with the decrease of particle size. The highest value of electromechanical coupling factor was 0.518 at milling time 5hour. The highest values of mechanical quality factor and dielectric constant were 1566, 1590 at milling time 4hour, respectively.
