FIELD: powder metallurgy. SUBSTANCE: an initial blank, had been compacted and baked of a necessary compound, is being disintegrated to a powder with particle size 1-3 micrometers; the powder is being poured to a non-magnetic press-mold, arranged between poles of an electromagnet. The press-mold is being cooled up to a temperature of liquid nitrogen, an electromagnetic field with inductivity near 1 Tl is being created, and then the powder is being compacted. The received compacted piece is being baked again at 900 C. EFFECT: enhanced current carrying capacity due to provision of crystalline texture of the material. 1 cl
