A Ba‐free sealing glass with a high coefficient of thermal expansion and excellent interface stability optimized for SOFC/SOEC stack applications

“…All the XRD files were analyzed with X'Pert HighScore Plus (Panalytical) and the Rietveld refinement was carried out using the WINPOW software …”

Effect of carbon on interstitial ordering and magnetic properties of ε-Fe2(N,C)1-

“…All lattice parameters for ε-Fe2(N,C)1-z are plotted versus total interstitial content (1z) in Fig. 8(a) and compared to additional values obtained with X-ray diffraction [38].…”

“…Fig. 8: a) Lattice parameters versus interstitial content for ε-Fe2(N1-xCx)1-z (solid symbols) compared to additional values obtained with X-ray diffraction [38] (open symbols) and published relations for pure nitrides by Somers et al [15] and Liapina et al [35] and for carbonitrides by Firrao et al [39]. Labels denote the fraction of interstitial carbon atoms, x. b) The difference in lattice parameter c and the published relation [15] for ε-nitrides (Δc = cc(z)) plotted versus the carbon content, x.…”

“…Labels denote the fraction of interstitial carbon atoms, x. Current values obtained with neutron diffraction (solid symbols) are compared to additional values obtained with X-ray diffraction [38] (open symbols).…”

Gaseous thermochemical synthesis and characterization of mixed interstitial phases in the Ti-C-O system

“…The use of thin foils enables fast trough-diffusion of interstitial elements and hence possibility for synthesis of homogenous materials, provided that equilibrium between the solid state and the gas atmosphere is attained ([6], [7], [8], [9]). Hitherto, no systematic work on the Ti-C-O system using thin foils and controlled gas systems has been performed.…”
