Patent ID: 7799158

Claim:
A method for producing a crystallographically-oriented ceramic in which crystals are oriented comprising: a shaping step of forming a first shaped layer with a thickness of 10 μm or less containing a first inorganic material in which grain growth occurs at a predetermined first temperature or higher and a second shaped layer containing a second inorganic material in which grain growth occurs at a second temperature higher than the first temperature; a laminating step of laminating one or more each of the first shaped layer and the second shaped layer to form a laminated body; and a firing step of 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 in which grain growth has occurred, wherein grain growth in the first layer is promoted within the main plane of the layer and is limited in the thickness direction of the layer.
