Fluorinated transition alumina with Al2−x/3O3−xFx compositions: Thermal, chemical, structural and morphological investigations

Enhancing the combustion of nAl with AlF3 coating: gas–solid reaction mechanism for reducing combustion agglomeration of Al powder

“…According to previous literature in the field of metallurgy, 37–41,51 AlF 3 will undergo a slow pyro-hydrolysis process at temperatures over 800 °C. It combines with residual hydroxyl groups in the alumina surface, generating gaseous AlOF and HF via reaction (1).…”

Perfluoroalkyl Acid-Functionalized Aluminum Nanoparticles for Fluorine Fixation and Energy Generation

“…Reactions in this stage exhibit strong continuity except PFGA with multiple functionalities, which leads to its low decomposition temperature. The following stage is the reactions of Al 2 O 3 and Al with fluorine-containing intermediates to generate Al–C–F bonds succeeded by the Al 2– x /3 O 3– x F x complex . The current stage produces substantial heat, which is enough to cleave the C–F bond.…”

“…Also, carbon is replaced with the pyrolysis of PFOA reflecting as the peak at 75°, which presents initially at 300 ∼ 400 °C. 33 The current stage produces substantial heat, which is enough to cleave the C−F bond. With the increment of free fluorine, the Al-based complex is finally transferred to AlF 3 .…”

Aluminium(III) fluoride originating from decomposition of hydrazinium fluoroaluminate(III) under oxidative conditions: Syntheses, X-ray photoelectron spectroscopy and some catalytic reactions

“…As for the GS samples discussed above, the low binding energy of the Al 2p peak can be assigned to aluminium bound primarily to oxygen, an environment relating closely to g-alumina, and the high BE component to an aluminium in a partially fluorinated environment [28]. It is not necessary to postulate the existence of a homogeneous ordered, oxofluoride phase, for example related to that recently identified as an intermediate during the pyrohydrolysis of a-AlF 3 [37].…”
