$Pb(Sn_{1/2}Nb_{1/2})O_3-PbTiO_3-PbZrO_3$계 세라믹스의 유전 및 초전특성에 관한 연구

A Study on Dielectric and Pyroelectric Properties of $Pb(Sn_{1/2}Nb_{1/2})O_3-PbTiO_3-PbZrO_3$ Ceramics

In this study, x PSN - y PT - z PZ ceramics doped with w $MnO_2$ were fabricated by the mixed oxide method at 1250 [$^{\circ}C$] for 2[hr] and then the dielectric and pyroelectric properties were investigated. In the 0.05 PSN - 0.4 PT - 0.55 PZ specimen with 0.5[wt%] $MnO_2$ the Pyroelectrics coefficient was $6.6{\times}10^{-8}[C/cm^2.^{\circ}C]$, respectibly.
