Thermodynamic study of synthesis of titanium boride by the method of condensation combustion of gases

We have performed a thermodynamic calculation of the adiabatic combustion temperatures and equilibrium composition of products in the BCl$_3$ – TiCl$_4$ – Na system at atmospheric pressure and temperatures of 300–3000 K. The maximum combustion temperature is equal to 1872 K. The conditions under which the final high-melting products Ti, TiB, TiB$_2$, and B are produced have been found. The results obtained enable one to choose the conditions for synthesis of highly disperse powders of high-melting compounds and coatings based on them using combustion processes.
