PCT No. PCT/SU89/00112 Sec. 371 Date Jun. 4, 1991 Sec. 102(e) Date Jun. 4, 1991 PCT Filed Apr. 25, 1989 PCT Pub. No. WO90/05120 PCT Pub. Date May 17, 1990.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.
