FIELD: chemistry.
SUBSTANCE: invention relates to ferromagnetic powder composition and method of its obtaining. Claimed is ferromagnetic powder composition, including iron-based soft magnetic particles of core, which have bulk density 3.2-3.7 g/ml, with the surface of core particles being provided with inorganic insulation phosphorus-based layer and at least one organometallic layer of organometallic compound of claimed structure, located outside first inorganic insulation phosphorus-based layer. Disperse bismuth oxide is linked with organometalic layer. Invention also relates to method of composition obtaining and method of manufacturing soft magnetic materials, prepared from claimed composition as well as to material obtained.
EFFECT: claimed composition makes it possible to obtain materials with high specific resistance and low loss in core in environmentally friendly way.
