Abstract

L'invention concerne une ferrite de manganèse et de zinc Cette ferrite, dont les composants initiaux impurs, usuels dans le commerce, incluent : 50 à 55 % en moles de Fe2 O 3 et dans laquelle éventuellement une quantité allant jusqu'à 5 % en moles de Fe2 O3 est remplacée par du SnO2 et/ou du TiO2 contient 10 à 40 % en MnO et le reste en ZnO avec un supplément de 0,06-0,1 % en poids de CaO, et 0,005-0,03 % en poids de SiO2 . Application notamment aux ferroferrites de Mn-Zn-Sn-Ti.
