Abstract
Self-propagating high temperature synthesis of titanium carbide from finely divided powders of Ti and C is initiated in the solid state by diffusion at the contacts between particles. In the model of concentric spheres of titanium and carbon, the formation of TiC has been computerized as a function of graphite particles radius r(m), time t(s) and absolute temperature T(K). The reaction rate α (moles of carbon reacted relative to the initial amount of carbon) can be expressed by the relationship : [MATH]
