Abstract: The main chemical reactions of interaction in the Al₂O₃−N₂ system have been determined for a temperature of 2400 K and a pressure of 1 Bar. It was found that in the absence of direct interaction of nitrogen (molecular and atomic) with the melt, chemical reactions between nitrogen and products of dissociative evaporation of Al₂O₃ melt are possible. Nitrogen oxidation reactions and interaction reactions of nitrogen oxides with the melt, both directly and with the participation of elemental oxygen or gaseous aluminium oxides, have been determined. It is demonstrated that elemental forms of nitrogen can interact with the melt together with nitrogen oxides and (or) with all Al-containing components of the system. Concentrations of gaseous substances in equilibrium with Al₂O₃ melt were calculated by the Monte Carlo method.
