METHOD OF OBTAINING CAST REFRACTORY INORGANIC MATERIALS Abstract of the Disclosure A method of obtaining cast refractor inorganic materials comprises mixing at least one oxide of a metal selected from the IV, V and VI groups of the periodic system with a metallic reducer and a non-metal or an oxide thereof. Then a small por- tion of the mixture surface is ignited to produce a combustion zone. Combustion is conducted in a gaseous medium under a pres- sure of 1 to 5,000 atm. The proposed method permits obtaining cast carbides, bo- rides, silicides and nitrides of metals of the IV, V and VI groups of the periodic system, as well as cast hard alloys based thereon. The resulting compounds exhibit high hardness, strength and wear resistance.
