Abstract: {Technical Problem} To provide an alkaline-niobate-based piezoelectric/electrostrictive ceramic composition that has excellent electric field induced strain during application of high electric field. {Solution} A piezoelectric/electrostrictive ceramic sintered body has a microstructure in which a matrix phase and an additional material phase having different compositions coexist and the additional material phase is dispersed in the matrix phase. A residual strain ratio of the additional material phase alone is larger than a residual strain ratio of the matrix phase alone. The matrix phase and the additional material phase have a composition in which a Mn compound containing Mn atoms of 0 parts by mol or more and 3 parts by mol or less and a Sr compound containing Sr atoms of 0 parts by mol or more and 1 part by mol or less are contained in a composite of 100 parts by mol represented by a general formula {Li y (Na 1-x K x ) 1-y } a (Nb 1-z-w Ta z Sb w )O 3 , where a, x, y, z and w satisfy 0.9‰¤a‰¤1.2, 0.2‰¤x‰¤0.8, 0.0‰¤y‰¤0.2, 0‰¤z‰¤0.5 and 0‰¤w‰¤0.1, respectively. Zero or one kind of element is not common to constituent elements of the matrix phase and constituent elements of the additional material phase in comparison therebetween.

Abstract: Manufacturing sintered bodies having microstructures including microscopic grains having a grain diameter of less than 5 µm, intermediate grains having a grain diameter of 5 µm or more and less than 15 µm, and coarse grains having a grain diameter of 15 µm or more and 100 µm or less enables to obtain high electric characteristics. Chemical compounds including metal elements are mixed so that the ratio of the elements is a composition expressed by (Li, Na, K) (Nb, Ta) O 3 , the mixture is calcined and crushed to obtain calcined/crushed powder. The powder is sintered in a constant temperature keeping process wherein temperature is kept constantly at a predetermined temperature within a range from 800 to 900°C for a predetermined period of time in a heating process, and then the powder is further sintered by raising temperature to firing temperature, thereby the piezoelectric materials having superior electric characteristics are manufactured.

Abstract: PROBLEM TO BE SOLVED: To provide a nondestructive inspection that can make simple and quantitative evaluation on a single-crystalline work-affected layer. SOLUTION: An analysis method is provided for an X-ray locking curve obtainable from a single crystal for detecting a work-affected layer, namely, the method is provided for evaluating the work-affected layer based on a ratio of a skirt-part strength vs peak intensity. In this case, the position of the skirt part is that where the X-ray analysis strength attenuates up to the background level, or the position away from the peak position by ±5,000 seconds.
