Thermochemical Properties of Titanium and Carbon

Pyrolants composed of titanium (Ti) and carbon (C) react to form titanium carbide (TiC) according to  

This reaction is highly exothermic without yielding gaseous products, i. e., it is a gasless reaction, and the adiabatic flame temperature is 3460 K at the stoichiometric mixture ratio. However, this reaction only occurs at high temperatures, above 2000 K. In order to initiate the combustion, a high heat input is needed for ignition. 

It is shown that 3 -increases with increasing and that the maximum I is obtained at xi(0-80). Since a Ti-C pyrolant is a heterogeneous mixture, the reaction rate is highly dependent on xi. as well as on the particle sizes of both Ti and C.
