Production of ferro-electric composition material for use micro- electronic components uses fritted ferro-electric particles coated with dielectric compound aided by solvent and precursor

摘要

The procedure, in which particles of a ferro-electric compound are coated with a dielectric compound, is carried out by placing the particles of the ferro-electric compound in contact with a fluid containing at least one solvent and a precursor of the dielectric compound, with the fluid maintained under pressure and at a temperature above 10 degrees C. The ferro-electric compound is selected from the following materials: PbTiO3, PZT, PMN, LiNbO3, KNbO3, KTN, BaTiO3, BaTiO3-SrTiO3, and the dielectric compound is selected from oxides and nitrides.
