FIELD: building materials industry; metallurgy industry; other industries; methods of production of the initial refractory materials and the refractory products manufactured with their usage.
SUBSTANCE: the invention is pertaining to production of the refractory products and may be used in building materials industry, metallurgy industry, other industries for production of the refractory materials and products. The refractory materials are produced by molding the composition, which contains the refractory filler and the initial refractory material with the graphite grains having the average size of 500 nanometers or less, or with the graphite grains produced by the graphitization of the carbonic carbon black. The graphite grains contain at least one component selected from the group consisting of metals, boron and silicon. The refractory materials alongside with the refractory filler may contain also the carbon grains (A), selected from the carbonic carbon black and the graphite grains produced by the graphitization of the carbonic carbon black and having absorption - DBP (x) 80 ml/100g or more; the carbon grains () selected from the carbonic carbon black and the graphite grains produced by the graphitization of carbonic carbon black, and having absorption -DBP (x) less than 80 ml/100g. The invention allows to improve the thermal impact stability of the refractory materials, their corrosion resistance and the oxidation resistance.
EFFECT: the invention ensures the improved thermal impact stability of the refractory materials, their corrosion resistance and the oxidation resistance.
