Burning of the Ti + xC (1 &gt; x &gt; 0.5) powder and granulated mixtures

For the first time combustion of a thermally conjugated granulated mixture consisting of the mixture of Ni + Al and Ti + C granules, differing in burning velocity and temperature has been investigated experimentally in co-current flows of argon and nitrogen. It has been established that in the whole investigated gas flow rates the ignition of Ni + Al granules occurs in the combustion front. The high efficiency of Ti + C donor granules energy usage has been shown, since the time of heat exchange between the granules does not depend on the sample size, but is determined only by the characteristics of internal heat transfer. A strong increase in the burning rate of the composite mixture at low nitrogen flow rates has been explained via interaction of aluminum with nitrogen and effective reduction of heat loss of the donor. The possibility of isolating the target synthesis product was shown even if its melting point is below the adiabatic temperature of combustion of the composite mixture.
