Abstract

Method of manufacturing ferromagnetic material or a ferromagnetic body as described, the initial material being a ferrite that produces by heating oxides and/or substances that can be converted into oxides such that they can react as a consequence of the fusion, and the product of Reaction ground and fused again, this series of stages can be repeated once or several times with the particularity that it starts from a mixture that during heating can form a ferrite material with an initial permeability in a compact state greater than 500 and that the material it is fused at least twice at a temperature greater than 1100ºC but in such a way that the pore volume of the reaction product is greater than 10%.
