 1751.    KHRIZMAN, I. A., AND KORNIĬCHUK, G. P.  [Role of Iron Nitride in the Catalysis of Ammonia.]  Ber. Inst. Physik. Chem., Akad. Wiss. Ukr. S. S. R., vol. 6, 1936, pp. 95-101; Chem. Abs., vol. 31, 1937, p. 6831.

       NH₃ was decomposed catalytically in the interval 250°-470°, the catalyst being the nitride of activated Fe of the type Fe-Al₂O₃-K₂O.  At 410° and higher, a stoichiometric mixture of N₂ and H₂ was obtained, at 410°-350° the products abounded in N₂, and at 350° and lower, the chief product was N₂ with traces of H₂.  By comparing these results with those obtained when ordinary Fe was used, it becomes evident that the nitride hinders the decomposition of NH₃ and that Fe and not the nitride, is the catalyst in the production of NH₃.
