摘要： A piezoelectric ceramic composition comprises a composite perovskite type oxide of Pb(Ni 1/3 Nb 2/3 )O 3 and simple perovskite type oxides of PbTiO 3 and PbZrO 3 as main components. The composition range of the main components exists in an area surrounded by lines for connecting respective composition points, i.e., a point A (X = 40, Y = 37, Z = 23), a point B (X = 36, Y = 37, Z = 27), a point C (X = 33, Y = 40, Z = 27), and a point D (X = 37, Y = 40, Z = 23) in a triangular coordinate system defined by apexes of Pb(Ni 1/3 Nb 2/3 )O 3 , PbTiO 3 , and PbZrO 3 , provided that Pb(Ni 1/3 Nb 2/3 )O 3 amounts to X molar %, PbTiO 3 amounts to Y molar %, and PbZrO 3 amounts to Z molar %. The composition makes it possible to realize a large strain amount while suppressing the relative dielectric constant to be low. The composition is preferably usable for an piezoelectric actuator of an ink-jet head.

摘要： Piezoelectric/electrostrictive ceramics are provided, which exhibit only a small change in properties after polarization, high insulating properties, and narrow variations in durability. A piezoelectric/electrostrictive element (1) has a laminated structure in which an electrode film (110), a piezoelectric/electrostrictive film (112), another electrode film (114), another piezoelectric/electrostrictive film (116), and another electrode film (118) are laminated in order of mention on a thin portion (104) of a substrate (102). The piezoelectric/electrostrictive films (112, 116) are ceramic films that include a perovskite oxide containing lead as an A-site component and magnesium, nickel, niobium, titanium, and zirconium as B-site components. Crystal grains in the piezoelectric/electrostrictive films (112, 116) have a core/shell structure with the shell portion having a higher concentration of nickel than the core portion and with the core portion having a higher concentration of magnesium than the shell portion. Such piezoelectric/electrostrictive films (112, 116) can be formed by firing a piezoelectric/electrostrictive material powder synthesized from a columbite compound.
