FIELD: metallurgy. SUBSTANCE: process includes nitriding of silicon-carrying material under self-maintained condition of burning under increased pressure of nitrogen. Powders of one or several metals chosen from row of calcium, aluminum, titanium, zirconium, vanadium, niobium, chrome, manganese, iron with silicon with silicon content of 15.0-95.0 per cent by weight are utilized in the capacity of starting silicon-carrying material. EFFECT: high-efficiency technology of preparation of nitrided alloying materials based on silicon nitride. 15 cl, 1 tbl
