Abstract:
A method for producing a crystallographically-oriented ceramic includes the steps of forming a first sheet with a thickness of 10 μm or less containing a first inorganic material in which grain growth occurs at a first temperature or higher and a second sheet containing a second inorganic material in which grain growth occurs at a second temperature higher than the first temperature, laminating one or more each of the first and second sheets to form a laminated body, firing the laminated body at a temperature equal to or higher than the first temperature and lower than the second temperature to cause grain growth in the first inorganic material, and then firing the laminated body at a temperature equal to or higher than the second temperature to cause grain growth in the second inorganic material in the direction of a crystal plane of the first inorganic material.
