The Energy-Efficient Processing of Fine Materials by the Micropyretic Synthesis Route

Figure 4

Time variations of the combustion front temperature along the TiB₂ specimen with the preexponential factor of 1 × 10¹⁰ s⁻¹. The interval time between two consecutive time steps (profiles) is 1.0 ms. The ignition power is taken as 175 Joule/(ms·g) in the numerical calculation. The activation energy in (a), (b), and (c) are taken as 254.4 KJ/mole (80% of reported experimental value) [27], 318.0 KJ/mole (reported experimental value), and 381.6 KJ/mole (120% of reported experimental value), respectively.
