Interstitial nitrides revisited - a simple synthesis of MxMo3N (M = Fe, Co, Ni)

Conway, Jack O.; Prior, Timothy J.

Abstract

The efficient synthesis of polycrystalline filled beta-Mn structured Ni2Mo3N, and the eta-carbides Fe3Mo3N and Co3Mo3N, by a single heating of metal powders at 975 ºC under a hydrogen-nitrogen mixture is reported. Rietveld analysis of high-resolution X-ray powder diffraction data shows that the reduction-nitridation of NiMoO4 produces Ni2Mo3N and nickel; Ni3Mo3N is not obtained in this way and its existence is disproved.
