Graphite combustion temperature
WebIncreasing the oxygen content of the primary combustion air increased the combustion temperature and decreased the reaction time. As the oxygen content increased from 21% to 30%, the average temperature increased by 47.72 K at a setup temperature of 1673 K, and the reaction time decreased by 30.22% at the same temperature. WebMay 10, 2013 · When the activated temperature exceeds 1100 K, the adiabatic temperature for the combustion synthesis is more than 1800 K and the reaction can self-sustain. In most cases, SHS is applied for fabrication of monophase or composite powders [ 32 ], which can be sintered using several technological processes [ 11, 31 ].
