FIELD: metallurgy.
SUBSTANCE: invention relates to powder technology, particularly to receiving of materials, containing metal nitrides. It is prepared mixture, containing chrome oxide (III) in amount 0.7-1.8 mol % and chrome powder - the rest. Received mixture in free-filled view is kindled by means of heated up to 600°C current of tungsten helix at a presence of air at atmospheric pressure in the capacity of nitride agent.
EFFECT: it is provided simplification of technology and reduction of products self-cost.
