METHOD FOR PRODUCING CRYSTALLOGRAPHICALLY ORIENTED CERAMIC

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a crystallographically oriented ceramic having properties that can be enhanced.

SOLUTION: The method for producing a piezoelectric/electrostrictive body 30 containing the crystallographically oriented ceramic includes: a particle-preparing step of preparing pseudocubic particles 31 each having a substantially cubic shape; a dispersing step of dispersing the pseudocubic particles 31 in a solvent; a particle section-forming step of forming a seed section 32 and a matrix section 34 directly or indirectly on a base 12, the seed section 32 being formed by arranging the dispersed pseudocubic particles 31 in a predetermined plane direction, the matrix section 34 being formed from matrix particles 33 each having a desired composition; and a firing step of firing the seed section 32 and matrix section 34 formed on the base 12. The crystallographic orientation of the matrix particles 33 contained in the matrix section 34 can be adjusted to the crystallographic orientation of the pseudocubic particles 31 which are contained in the seed section 32 and arranged in the predetermined plane direction.
