Abstract

x $Pb(Sb_{1/2}Sn_{1/2})O_3-PbTiO_3-PbZrO_3$, (0.05$\leq$x$\leq$0.30) ternary compound ceramics were fabricated by the mixed oxide method. The sintering temperature and time were $1200{\sim}1300[^{\circ}C]$, 2 hour, respectively. Increasing the PSS contents, the transition temperatures were decreased. The relative dielectric constant and Curie temperature of the 0.30PSS-0.20PT-0.50PZ specimens were 372, 190[$^{\circ}C$]. The pyroelectric coefficient, figure of merits for pyroelectric current and detectivity of the 0.25PSS-0.25PT-0.50PZ specimens had the good values, $5.41{\times}10^{-8}[C/cm^{2}K]$, $27.72{\times}10^{-12}[Ccm/J]$, $7.65{\times}10^{-10}{Ccm/J]$, respectively.
