Piezoelectric/electrostrictive porcelain composition, piezoelectric/electrostrictive device, and method of piezoelectric/electrostrictive device

摘要

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 PbMg_1/3Nb_2/3O₃-PbZrO₃-PbTiO₃ ternary solid solution system composition and NiO or including a Pb(Mg, Ni)_1/3Nb_2/3O₃-PbZrO₃-PbTiO₃ ternary solid solution system composition, and further contains lead germanate.
