FIELD: electromagnetic radiation protection.
SUBSTANCE: invention relates to a method of preparation and to composition of materials absorbing electromagnetic emission. Composition is prepared by combining binder with ferrite, the latter containing 60-90% of ferrite material obtained according to high-temperature ceramic technology and ground to microparticle size and 10-40% of particles belonging to ferrite phase obtained by chemical precipitation from aqueous solutions onto surface of ferrite material microparticles. Ferrite is calcined in the form of isolated precipitate at 500-600°C and then disaggregated. Invention further discloses ferrite-based composition containing 9-13% binder obtained by above-indicated method.
EFFECT: increased choice of electromagnetic radiation-protection materials.
