Effects of nitrogen on the combustion of aluminum

Aluminum powder metallurgy processing

“…There is experimental evidence available that indicates nitrogen plays a major role in the combustion of aluminum in air [38]. These authors reference a study by Prentice [39] that investigated aluminum burning in an argon-oxygen atmosphere during which he observed a clean metal surface, whereas burning in air created an oxide on the powder.…”

Products of combustion of mixtures of aluminum and tungsten nanopowders in air

“…It was shown [5] that thermodynamic calculations predict aluminum nitride to be a possible intermediate product, which has to undergo complete oxidation in air. Thus, stabilization of the AlN phase 1 Research Institute of High Voltages, Tomsk 634050; nanolab@hvd.tpu.ru.…”

Nitride Formation during Combustion of Ultrafine Aluminum Powders in Air. I. Effect of Additives

“…Theoretically, the idea of the thermodynamic probability of formation of AlN as an intermediate product of aluminum combustion in air was expressed in [10]. Indeed, according to thermodynamic calculations, aluminum nitride should to be oxidized to the oxide in an exothermic process.…”

“…Unfortunately, in studies of the effect of additives on the combustion of coarse aluminum particles in air, the composition of the combustion products, as a rule, has not been analyzed. An exception is the studies of [8][9][10], in which the phase composition of the products from aluminum combustion in air was examined using various methods. Thus, Yagodnikov et al [9], using the ASTRA program, calculated the thermodynamic combustion temperature and relative mass concentration of condensed combustion products of enriched aerosols.…”
