Abstract
The present invention relates to a process for the synthesis of perovskite ceramics and more particularly relates to the preparation of perovskites with general formula LnMO3, where Ln represents lanthanide element and M a transition metal.
Claims16
A process for the preparation of perovskite ceramics which comprises mixing of salts of lanthanide element and salts of transition metal, at least one external fuel, and optionally a chelating agent, in a polar solvent, subjecting the above solution mixture to microwaves for at least 2 minutes to obtain a foamy mass of the product, subjecting the foamy mass to mechanical pressure to obtain the product in fine powder form.
