Abstract

La présente invention concerne une nouvelle composition pulvérulente ferromagnétique comprenant des particules possédant un noyau à base de fer faiblement ferromagnétique dont la surface est recouverte d'un enrobage non organique isolant, et un composé lubrifiant sélectionné dans le groupe comprenant des silanes, des titanates, des aluminates, des zirconates, ou des mélanges de ces derniers. L'invention concerne également un procédé destiné à la préparation de substances composites faiblement ferromagnétiques, utilisant cette nouvelle composition pulvérulente.
