FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of magnetically hard ferrites. Invention may be used for purification of effluents, in magnetic filters, as well as crushing bodies in electromagnetic apparatuses. Composition comprises strontium hexaferrites, aerosil in gel state and thermally treated sludge formed in neutralising halogen organic compounds including calcium chloride and fluoride.
EFFECT: composition allows increasing magnetic and strength characteristics and simplifying production process.
