PROCEDURE OF PREPARATION OF COMPLEX PEROVSKITES BY MECHANOCHEMICAL SYNTHESIS

摘要

The subject of invention is a procedure of preparation of complex perovskites by a mechanochemical synthesis in such a manner that the compound produced contains no other compounds and impurities originating from the mill construction material, which might affect functional properties of the prepared material. The invention takes advantage of rapid and easy formation of lead titanate with the perovskite structure, which enhances the formation of the complex perovskite during the phase of synthesis. Lead titanate can be prepared by a mechanochemical synthesis or in some other way.
