Abstract

Procedimiento de fabricación de imanes magnéticos permanentes, de la clase cerámica de gran campo coercitivo, caracterizado porque consiste en comprimir, a una presión de 0,5 a 20 toneladas por cm², una mezcla de partículas de óxido de hierro y de bario, de modo que el producto final responde en porcentajes moleculares a la fórmula (85,7-x) Fe2O3.(14,3+x)BaO en la que x está comprendido entre 0 y 4 y en hacer sufrir al producto comprimido un tratamiento térmico de vitrificación a temperaturas comprendidas entre 1.150 a 1300 grados centesimales, imantando después hasta saturación el referido producto.
