Wet process for the production of a readily sinterable powder material of perovskite or its solid solution

摘要

A process for producing a powder material of perovskite or its solid solution represented by the formula: ABO3 wherein A is one or more metal elements coordinated with 12 oxygen atoms, and B is one or more metal elements coordinated with 6 oxygen atoms, which comprises contacting an aqueous or alcohol solution of either component A or component B with a precipitating solution to form precipitates, then adding an aqueous or alcohol solution of the other component to form precipitates, and drying the precipitates, followed by calcining at a temperature of from 400 DEG to 1200 DEG C.
