Process for manufacture of composite oxide.

摘要

A process for the manufacture of a composite oxide comprises carrying out, in a non-aqueous medium, a condensation reaction between an organometallic compound having a structure such that the metallic element present in the compound is bonded to the organic moiety therein via an oxygen atom, and a protic acid which is capable of carrying out the condensation reaction with the organometallic compound, and is a hydroxide containing an element different from the metallic element contained in the organometallic compound. The composite oxide can be produced with a high level of purity but without segregation.
