Abstract—: Based on experimental and theoretical data, thermodynamic analysis of possible chemical reactions occurring in the titanium–aluminum–hexamethylenetetramine system under conditions of self-propagating, high temperature synthesis (SPHTS) was performed. It was shown that, under the above conditions, the MAX-phase Ti3AlC2 can be predominantly formed at cooling down the material up to temperatures lower than 1100 K. The highest negative values at T = 298 K are those of enthalpy and Gibbs energy of the combustion reaction of hexamethylenetetramine combustion in the air, which allows for the assumption that this is the starting reaction for the synthesis process under study. 2020, Allerton Press, Inc.
