Abstract

L'invention concerne un ferroferrite de Mn-Zn-Sn-Ti pour une plage étendue de températures et de fréquences. Dans ce ferroferrite de Mn-Zn-Sn-Ti, la composition des composants initiaux est la suivante : environ 49 à 55 % en mole de Fe2 O3 , 10 à 40 % en mole de MnO, 0,5 à 5 % en mole de (DnO2 + TiO2 ), et le restant en ZnO, la teneur en Fe**2+ dans le réseau du ferrite étant commandée par le pourcentage de Fe2 O3 dépassant 50 % en mole et par le pourcentage de la somme des composants SnO2 et TiO2 et étant choisie de telle manière que le ferrite possède le facteur de pertes et le coefficient de température, respectivement désirés. Application notamment aux ferrites pour systèmes de multiplexage à haute fréquence.Provided is a Mn-Zn-Sn-Ti ferroferrite for a wide range of temperatures and frequencies. In this Mn-Zn-Sn-Ti ferroferrite, the composition of the initial components is as follows: about 49-55 mole% Fe2 O3, 10-40 mole% MnO, 0.5-5 mole% (DnO2 + TiO2), and the remainder in ZnO, the Fe ** 2 + content in the ferrite network being controlled by the percentage of Fe2 O3 exceeding 50 mol% and by the percentage of the sum of the components SnO2 and TiO2 and being chosen such that the ferrite has the loss factor and the temperature coefficient, respectively desired. Application in particular to ferrites for high frequency multiplexing systems.
