Abstract

Mejoras introducidas en la fabricación de material ferromagnéticoque consiste en cristales que tienen estructura de espinelacaracterizadas porque una mezcla finamente pulverizada de óxido de niquelóxido de cobreóxido de cobaltoy óxido de hierrolas cuales se pueden sustituir total o parcialmente por compuestos que se convierten en estos óxidos al calentarsey que tiene una composición que corresponde a 29 a 47 mol. % de NiO 3 a 20 mol. % de CuO 05 a 2 mol. % de CoO 50 a 52 mol. % de Fe2 O3 se funde a una temperatura entre 1000ºC y 1400 ºCpreferentemente a una temperatura entre 1200 º C y 1300º C.
