Method for obtaining a composite ferro-electric material

摘要

The invention relates to a method for obtaining a composite ferro-electric material, consisting of the following stages: particles of a ferro-electric compound are covered with a dielectric layer; a dense composite material is formed by sintering the covered particles. The invention is characterized in that in the covering stage the particles of the ferro-electric compound are brought into contact with a fluid containing at least one solvent and a precursor of the dielectric compound, said fluid being pressurized.
