| 20080206561 | PLATE-LIKE POLYCRYSTALLINE PARTICLE, METHOD FOR PRODUCING PLATE-LIKE POLYCRYSTALLINE PARTICLES, AND METHOD FOR PRODUCING CRYSTALLOGRAPHICALLY-ORIENTED CERAMIC - A plate-like polycrystalline particle is produced by forming inorganic particles into a self-supported, sheet-like shaped body with a predetermined thickness, firing the shaped body, and crushing and classifying the fired shaped body by passing through a mesh having openings with a predetermined size.
