The morphologies and structural properties of Fe3O4 were characterized by using X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and...

The XRD and XRF analysis of MEP identified the dominant existence of crystalline magnetite. Furthermore, the morphological analysis of MEP confirmed the agglomerate porous morphology of...

Nov 1, 2008 · Lattice parameter of the wüstite was obtained from XRD data, by which a value of 0.072 was obtained for x in Fe 1−x O. A mean crystallite size of 13±1 nm was calculated for the single-phase wüstite, using Scherrer's formula.

Jul 28, 2019 · Typical XRD pattern of samples A and B without heat treatment as synthesized and stored under ambient conditions for 7 weeks. Main reflexes are marked (asterisk symbol, spinel; degree sign, wustite; number sign, iron)

We evolve a physical picture of the defect structure of wüstite, presenting a step by step description of how the complex diffuse diffraction patterns arise and are influenced by various possible real-space variables such as defect distribution, defect cluster size, number of interstitials and lattice strain.

This study demonstrates the use of monochromatic synchrotron X-ray radiation of 40 keV for high-precision equation-of-state studies on sets of single crystals analysed individually in the same diamond-anvil pressure cell.

Download scientific diagram | (a) XRD pattern of 2.5 at% Fe-doped sample (wustite series) and the corresponding fit. Vertical lines indicate the reflections corresponding to rutile-TiO 2 phase.

Jun 1, 2010 · In this paper, we report a simple method to control the size of the monodisperse iron oxide nanocubes (9–22 nm) obtained from thermal decomposition of the FeOL complex in the presences of oleic acid (OA) as a surfactant and sodium oleate …

Sep 25, 2003 · The XRD pattern of the unreduced magnetite-based catalyst (not reported) shows the diffraction lines of magnetite with a small amount (1–2%) of wustite.
