Title (EN) CONDUCTING FLUID CONTAINING MICROMETRIC MAGNETIC PARTICLES
(FR) FLUIDE CONDUCTEUR CONTENANT DES PARTICULES MAGNETIQUES MICROMETRIQUES
Abstract:
(EN) The invention relates to a composite material consisting of magnetic material micrometric particles (A) and a conducting fluid (B). The inventive material is characterised in that the material (A) is selected from magnetic compounds and alloys, is embodied in the form particles whose average diameter ranges from 1 to 10 µm and the carrier fluid is embodied in the form of a conductor fluid selected from metals, metal alloys and salts, which are liquid at temperatures less than the material (A) Curie temperature, of from the mixtures thereof.
(FR) L'invention concerne un matériau composite constitué par des particules micrométriques de matériau magnétique A et un liquide conducteur B. Le matériau est caractérisé en ce que le matériau A est choisi parmi les composés magnétiques et les alliages magnétiques, et il est sous forme de particules dont le diamètre moyen est entre 1 et 10 µm, et en ce que le fluide support B est un fluide conducteur choisi parmi les métaux, les alliages métalliques et les sels qui sont liquides aux températures inférieures à la température de Curie du matériau A, ou parmi leurs mélanges.
