Abstract: The effect of sodium hydrogen carbonate and ammonium chloride on the combustion of iron aluminum thermite in air at atmospheric pressure is experimentally studied. The effect of salt additives on the average linear velocity of combustion, the relative yield of the metallic phase in the ingot, and the relative weight loss during thermite combustion are investigated. The concentration flammability limits of the mixtures under consideration are determined.

Keywords: iron aluminum thermite, addition of salt, combustion velocity, concentration flammability limit, oxide and metallic phases.
