The Dielectric and Piezoelectric Characteristics of PMN- PSN-Pfl Ceramic as a Fucntion of Glass Frit

Glass Frit 첨가량에 따른 PMN-PSN-PZT계 세라믹의 유전 및 압전특성

The purpose of this study is to develop the material for multiayer piezoelectric ceramic transformer because multiayer piezoelectric transformer must need low sintering temperature. So that PMN-PSN-PZT family ceramics were added with glass brit(SiO$_2$ $.$ PbO). The dielectric and piezoelectric properties were increased with increasing it until the amounts of additive 0.8wt%. Sintering temperature were low about 100[$^{\circ}C$]. Accordingly, This material could be used to multiayer piezoelectric transformer .
