The present invention relates to preparing refractory chromium-containing material and resides in local initiation of an exothermal reaction in a mixture of the following composition: a chromium-containing component, 8-20 mass % of a reducer selected from the group consisting of aluminium, magnesium, silicon, titanium, zirconium, or the alloys thereof, and 0.1-50 mass % of a filler, wherein as the filler use is made of periclase, sand, clay, refractory oxide, refractory scrap, wastes of blast-furnace processes, wastes of graphite or silicon carbide production, or an inorganic salt taken separately or in a mixture.
A method of producing a refractory chromium-containing material comprising preparing an exothermal mixture of a chromium-containing component, a filler and a reducer, and thermally treating the mixture under combustion conditions to form the refractory chromium-containing material, said reducer comprising at least one metal selected from the group consisting of aluminum, magnesium, silicon, zirconium, titanium, and alloys thereof and being present in said mixture in an amount of about 8 to 20% by weight, said filler being selected from the group consisting of periclase, sand, clay, refractory scrap, silicon carbide production waste and an inorganic acid salt and being present in said mixture in an amount of about 0.1 to 50% by weight.
