| titleOfInvention | Piezoelectric / electrostrictive ceramic sintered body and piezoelectric / electrostrictive element using the same |
| abstract | A novel index or item such as a coefficient of thermal expansion and a Curie point, which can be a factor for improving characteristics, is found, and a piezoelectric / electrostrictive ceramic sintered body having improved electrical characteristics based on them is provided. A matrix and a filler are mainly perovskite oxides containing at least one element selected from the group consisting of Li, Na and K as an A site constituent element and Nb as a B site constituent element. It is composed of a first alkali niobate piezoelectric / electrostrictive material and a second alkali niobate piezoelectric / electrostrictive material in which a large number of particles are bonded to each other as a crystal phase, and a second alkali niobate The thermal expansion coefficient of the piezoelectric / electrostrictive material is lower than that of the first alkali niobate piezoelectric / electrostrictive material, and the volume fraction of the filler relative to the total of the matrix and filler is 0.5% by volume or more. 45% by volume or less of a piezoelectric / electrostrictive ceramic sintered body. [Selection figure] None |
