METHOD FOR PRODUCING SINTERED ELECTROCERAMIC MATERIALS FROM HYDROXIDE AND OXALATE PRECURSORS

A method for producing electroceramic materials of high sintered density from hydroxide and/or oxalate precursors is disclosed. In this method the precursor(s) are compacted to form a preform, thermally treated, recompacted and then sintered to form finished products. L'invention concerne un pr...

Summary:A method for producing electroceramic materials of high sintered density from hydroxide and/or oxalate precursors is disclosed. In this method the precursor(s) are compacted to form a preform, thermally treated, recompacted and then sintered to form finished products. L'invention concerne un procédé relatif à l'élaboration de matériaux électrocéramiques à haute densité de frittage, à partir de précurseurs hydroxyde et/ou oxalate. Selon ledit procédé, le ou les précurseurs sont compactés de manière à constituer une préforme, soumis à un traitement thermique, à nouveau compactés puis frittés aux fins d'élaboration des produits finis.
