Abstract

In this paper, in order to develop low temperature sintering $PbTiO_3$-system piezoelectric ceramics for thickness-vibration-mode piezoelectric transformer, $Pb_{0.76}Ca_{0.24}[(Mn_{1/3}Sb_{2/3})_{0.04}Ti_{0.96}]O_3$ ceramics using $0.25\;wt\%\;CaCO_3$ and $0.2\;wt\%\;Li_{2}CO_3$ as sintering aids were manufactured according to the variation of poling field. The specimens could be sintered at $930\;^{\circ}C$. The piezoelectric properties were investigated according to the poling field. The maximum properties showed at the field of 6.5 kV/mm, which had kt of 0.49, Qmt of 1816, and $d_{33}$ of 81.4 pC/N.
