The purpose of development - to increase the oxidation resistance of carbon-containing non-fired refractories samples to 35-40 % by means of main Al antioxidant activity amplifying while Al and other antioxidants (SiC and Ni (NiO)) nanoparticles synthesized are being used during their performance and unshaped low-cement refractories samples due to the directed formation of the phase composition and structure of clinker, cement stone and concrete. Research methods and instruments - the thermodynamic, X-ray diffraction, differential thermal, electron microscopy. Physical, mechanical and technical characteristics were determined according to the current State Standard and international standards (ISO). Experimental data processing was performed by means of the mathematical statistics methods. Theoretical and practical results - Physical and mechanical characteristics, phase composition and structure of non-combustible periclase carbon refractories and unformed refractories on chromium-containing binders were investigated, the influence of the interconnection "composition of modifiers - ways of modification of phenol-formaldehyde resin and binder - technological parameters - structure - properties" on stability to actions of given operational factors. Novelty - the theoretically grounded and experimentally proved the possibility of influencing the process of creating dense samples of refractory materials, with the help of reinforcing matrices, carbon bonds and binder systems by nanoparticles of a given composition, which simultaneously bear the role of a reinforcing element of a reinforcing structure, with a minimum of energy expenditure, their physical and mechanical properties, and the antioxidant or modifier that affects the phase equilibria of the multicomponent systems. The effectiveness of the new application - the refractories developed using enable to prolong to 1.5 - 2 times the lining service life, to minimize the technological shutdown and prepares number, the energy consumption and cost of lining. The field of application - the developed technology are used in refractory and cement industries enterprises without additional investments. The investigation results are used in the high school to the preparation of specialists in technology of refractory non-metal and silicate materials.
