“…This study measured the combustion wave velocity and reaction temperature, and identified the phase constituents of SHS-derived products. Details of the experimental setup were reported elsewhere [22]. In addition, the apparent activation energy (Ea) of the synthesis reaction was determined from the dependence of combustion wave velocity on the reaction temperature [10,11].…”

Formation of Ta5Si3 by self-propagating high-temperature synthesis (SHS) from elemental powder compacts of Ta:Si = 5:3 was experimentally and numerically studied. Experimental evidence showed that the increase of either sample density or preheating temperature led to the increase of combustion wave velocity and reaction temperature. The apparent activation energy, Ea ≈ 108 kJ/mol, was determined for the synthesis reaction. Based upon numerical simulation, the Arrhenius factor of the rate function, K0 = 2.5 × 10 7 s −1 , was obtained for the 5Ta + 3Si combustion system. In addition, the influence of sample density on combustion wave kinetics was correlated with the effective thermal conductivity (keff) of the powder compact. By adopting 0.005 ≤ keff/kbulk ≤ 0.016 in the computation model, the calculated combustion velocity and temperature were in good agreement with experimental data of the samples with compaction densities between 35% and 45% theoretical maximum density (TMD).

“…It should be noted that samples of Reaction (1) required an ignition enhancer, which was a pellet made up of titanium and carbon black with a molar ratio Ti:C¼ 1:1, to facilitate the initiation of solid state combustion. Details of the experimental setup and diagnostic techniques were previously reported [25]. (1) and (2), respectively.…”
