| 简介 |
A piezoelectric/electrostrictive ceramic composition is provided which exhibits high density and excellent crystallinity even in the case of firing under lower temperature conditions than in conventional cases, and which also exhibits excellent piezoelectric/electrostrictive properties. An ABO3 compound (first main component) with Bi at the A site and with B1 and B2 elements at the B site (B1 consists of at least one kind of element having an ionic valence of two or less and selected from the group consisting of Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn, and rare-earth elements; and B2 consists of at least one kind of element having an ionic valence of four or more and selected from the group consisting of V, Nb, Ta, Sb, Mo, and W) is dissolved in the form of a solid solution into another ABO3 compound (second main component) with at least Pb at the A site. |
