Time-and Temperature Resolved X-Ray Diffraction: The Nitridation of a Mixture Nb&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt;/Fe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; with Ammonia

The stoichiometric iron nitrides γ′‐Fe4N, ε‐Fe3N and ζ‐Fe2N were characterized by Mössbauer spectroscopy. The thermal decomposition of ε‐Fe3N was studied in‐situ by means of a specially developed Mössbauer furnace. We found ε‐Fe3N to γ′‐Fe4N and ε‐Fe3Nx (x ≥ 1.3) as decomposition products and determined the border of γ′/ε transformation at T ≅ 930 K. Mössbauer spectroscopy was applied to study in‐situ the thermal decomposition of the nitridometalate Li3[FeIIIN2] and the formation of Li2[(Li1‐xFeIx)N], the compound with the largest local magnetic field ever observed in an iron containing material. The kinetics of formation and the stability of Li2[(Li1‐xFeIx)N] was of particular interest in the present study.

The design, construction, and use of a furnace from which time-resolved x-ray diffraction data may be measured from reacting mixtures of solids or of solids and liquids is described. The furnace is a vertical tube design, constructed from commercially available components, and can operate at temperatures of up to 1000 °C. The apparatus is designed to heat sample tubes of up to 3 cm diameter. The use of high-intensity synchrotron-generated white-beam x rays allows the tube and its contents to be penetrated; thus x-ray diffraction data can be measured from reactions taking place in laboratory-sized reaction vessels. The energy-dispersive diffraction geometry allows rapid data collection (of the order of seconds); hence reactions can be followed continuously in real time. The use of the furnace is demonstrated by results from experiments performed on Station 16.4 of the Daresbury Synchrotron Radiation Source, UK. Two distinct reaction types are studied, both used to prepare the layered perovskite RbCa2Nb3O10: first, a solid state route at 800 °C and second a flux route, performed in molten RbCl, also at 800 °C.
