  • Ammonia Decomposition - an overview | ScienceDirect Topics

    The ammonia decomposition reaction can be conceived as the sum (linear combination) of two (counteracting) reactions both involving atomic nitrogen dissolved in iron: (i) the transfer of atomic nitrogen by ammonia to the iron substrate (nitrogen absorption), and (ii) subsequent denitriding (nitrogen desorption) by formation of N 2 gas, as follows (Grabke, 1968a, 1973, 1976, 1980):
