Summary:Specific features of the combustion of a titanium–carbon black granular mixture in a quartz tube blown with nitrogen is studied. In contrast to the previous studies, titanium with increased hydrogen content is used. The gas flow (cocurrent filtration) is produced by applying a fixed pressure differential less than 1 atm across the inlet and outlet of the tube. The characteristics of the combustion of a Ti + 0.5C granular mixture in a nitrogen flow are investigated. It is shown that an increased content of hydrogen in titanium leads to the formation of a two-front combustion wave. It is demonstrated that the first and second fronts of the two-front structure arise due to the interaction of the charge with nitrogen. The velocities of propagation of the fronts increase with the nitrogen pressure differential.
