$Pb({Sn}_{1/2}Nb_{1/2})O_3-PbTiO_3-PhZrO_3$ 세라믹의 유전 및 초전특성에 관한 연구

The PSN-PT-PZ ceramics doped with the Mn-oxide(0.5wt%) were fabricated by the mixed oxide method at 1250($^{\circ}C$) for 2(hr) and then the dielectric and pyroelectric properties were investigated with the compositions. In the 0.05PSN-0.4PT-0.55PZ specimen with 0.5(wt%) $MnO_2$, the pyroelectric coefficient was $6.6{\times}10^{-8}(C/Cm^2^{\circ}C)$, and the figure of merits for pyroelectric current and voltage were $27{\times}10^{-9},\;45{\times}10^{-12}$(C.Cm/J), respectibly.
