METHOD OF MANUFACTURING HIGHLY ORDERED CERAMIC STRUCTURAL BODY CONSISTING OF ORIENTED SINGLE CRYSTAL GRAIN

摘要

PROBLEM TO BE SOLVED: To provide a single-or a multi-layer highly ordered ceramic structural body cosisting of highly oriented ceramic single crystal grains, where the orientation of the single crystal grains and the thickness of the layer are easily controllable without using a mold or a container for slip casting.

SOLUTION: A strong magnetic field is applied to a suspension in which ceramic single crystal grains charged with electricity are dispersed in a solvent to orient each grain making good use of its magnetic anisotropy. An electric field is applied to the suspension in the oriented state, where the charged/oriented ceramic grains are sedimented and a ceramic structural body in which the orientation of the single crystal grains and the thickness of the layer are highly controlled is obtained.
