The self-propagating reactions, termed self-propagating high-temperature synthesis (SHS), or more simply, combustion synthesis, have received increasing attention especially for the preparation of refractory ceramic and intermetallic compounds. The kinetics and mechanisms of combustion reactions in the Ti-C and Ti-C-Ni systems were studied. Samples were produced by igniting compacts of elemental Ti, C, and Ni powders with a tungsten heating coil under an inert argon atmosphered. Using an elementary model of the process, the apparent activation energies of these highly exothermic reactions have been determined by measuring combustion wave velocities and combustion temperatures.
