Abstract
PURPOSE:To obtain perovskite-type ceramics powder without containing a large amount of oxygen defects, by thermally decomposing a complex or mixed metallic oxalate, pulverizing the resultant decomposition product and calcining the obtained powder in the an atmosphere under a specific oxygen partial pressure. CONSTITUTION:A complex or mixed metallic oxalate to provide perovskite-type ceramic powder by thermal decomposition calcining is thermally decomposed, then pulverized and subsequently calcined in an atmosphere under >=0.25 oxygen partial pressure. A complex or mixed metallic oxalate normally synthesized by a wet process can be employed as the complex or mixed metallic oxalate used and may be a substance capable of providing the aimed perovskite-type ceramic powder by calcining. The total pressure in a furnace in calcining is preferably >=1atm. If the oxygen partial pressure is below 0.25, oxygen defects of the perovskite-type crystal cannot be corrected. If the partial pressure exceeds 0.8, especially great effects on characteristics cannot be expected and it is not advantageous in aspects of safety and economics.
