Abstract
There is disclosed a piezoelectric/electrostrictive porcelain composition capable of manufacturing, at a comparatively low sintering temperature, a piezoelectric/electrostrictive body which is dense and superior in crystallinity and which has satisfactory piezoelectric/electrostrictive characteristics so that deviation of the composition is not easily generated. The piezoelectric/electrostrictive porcelain composition contains as a major component a piezoelectric/electrostrictive porcelain composition component including a PbMgNbO—PbZrO—PbTiOternary solid solution system composition and NiO or including a Pb(Mg, Ni)NbO—PbZrO—PbTiOternary solid solution system composition, and further contains lead germanate.
