Jan 1, 2010 · Here, small reflections of β-AlF 3 are already visible in the XRD powder pattern (see Fig. 1). Accordingly, the calculation of the 27 Al SATRAS NMR spectrum was successful with one crystallographic site superimposed by the two Al-sites of β-AlF 3 with distributed parameters.

Download scientific diagram | XRD patterns of the AlF3 catalysts with different morphology including cubic (AlF3-C), hexahedron (AlF3-H) and octahedron (AlF3-O) from publication:...

AlF3-coated Li1.134Ni0.3Mn0.556O2 and Li1.2Ni0.2Mn0.6O2 delivered a capacity of 225 and 248 mAh g⁻¹, respectively, stable over the 55 cycles investigated.

Films of aluminum fluoride (AlF3) deposited by thermal and plasma enhanced atomic layer deposition (PEALD) have been compared using in situ multiwavelength ellipsometry (MWE) and monochromatic...

Apr 15, 2024 · In this work, we conducted a comprehensive reinvestigation of the structural phase transition in α-AlF3 from rhombohedral to cubic phase by combining in situ Raman spectra, X-ray diffraction and first principles calculation.

Its crystal structure (aAlF3, space group R3̄c) consists of corner-shared {AlF6}—octahedra forming a three-dimensional network. As shown by X-raydiffraction, DSC-Raman and EPR measurements, the matrix undergoes a reversible phase …

The results show that the prepared re-deposition was composed of F and Al atoms, with 51.24 At% and 27.67 At%, respectively. XRD revealed that this was owing to the chemical formula AlF3, which has a rhombohedral crystal structure in the most stable alpha phase (α-AlF3).

In this paper, regularly shaped AlF3 particles with cubic structure were successfully synthesized via a solvothermal route. The as-prepared products were characterized by X-ray powder diffraction (XRD), energy-dispersive spectroscopy (EDS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

Jun 4, 2015 · Eleven selected pressure dependent X-ray diffraction patterns of AlF 3. The patterns are plotted as intensity versus a “normalized” diffraction angle 2 θ / λ (deg Å −1) because three different x-ray wavelengths (0.2895 Å, 0.3344 Å and 1.5406 Å) were used.

Feb 2, 2001 · In situ XRD experiments of the catalytically inactive α-AlF 3 phase were performed to investigate the structural changes of this material, associated with the extent of tilting of the AlF 6 octahedra in this ReO 3 -related structure, as a function of temperature.
