FIELD: ceramics. SUBSTANCE: method for production of highly porous cellular materials based on carbide ceramics includes application of thermosetting resin to foamed polyurethane. Preliminarily added to thermosetting resin is stoichiometric amount of metal powder with particle size of 1 to 5 mcm. Then, three-stage heat- treatment is performed: polymerization at 150 C, carbonization within temperature range of 150-1000 C and high-temperature treatment in vacuum furnace with graphite heaters in graphite container at 1600-1800 C. Offered method for production of highly porous cellular materials based on carbide ceramics allows increase of strength and heat stability of material. Produced materials feature low coefficient of heat conductness and high permeability for liquids and gases. EFFECT: higher efficiency. 1 tbl
