Title:
METHOD FOR PRODUCING PEROVSKITE-STRUCTURE COMPOUND SINTERED COMPACT
Document Type and Number:
WIPO Patent Application WO/2010/041645
Kind Code:
A1
Abstract:
Provided is a method for producing a sintered compact of a perovskite-structure compound having a high degree of orientation, comprising a step for preparing a monocrystalline powder formed from monocrystalline particles of a perovskite-structure compound; a step for producing a ceramic slurry containing said monocrystalline powder as the dispersion phase; a step for obtaining a ceramic molded article by molding the ceramic slurry in a magnetic field; and a step for sintering the ceramic molded article. Preferably a multicrystalline powder formed from multicrystalline particles of the same perovskite-structure compound as the perovskite-structure compound that forms the monocrystalline powder is prepared such that the ceramic slurry contains not only monocrystalline particles, but also multicrystalline particles, as the dispersion phase.
