Abstract
Mejoras introducidas en la fabricación de un ferrito ferromagnético que tiene una curva de histérisis prácticamente rectangular, que consisten en preparar una mezcla que contiene de 50,6 a 58 moles % de óxidos de metales trivalentes elegidos del grupo que consta de hierro ferrito, cromo,y aluminio, estando compuestos por lo menso cuatro quintos de dichos óxidos por óxido férrico, entre 1 y 6 moles por ciento de óxido de cobalto, entre 0 y 25 por ciento de un óxido por lo menos elegido del grupo que consta de óxido de manganeso, compresión de la mezcla en forma de núcleo, tratamiento térmico del núcleo a una temperatura entre 1.000 y 1.350 º C en una atmósfera de nitrógeno que contenga entre 0,01 % a 2% de oxígeno durante dos a seis horas y después enfriamiento lento durante unas quince hojas en nitrógeno puro.
