Abstract
This work is an original example to compare the results obtained after calcination of Al
2
O
3
hydroxides and oxidation of aluminoformers
alloys. FTIR and XPS signatures were obtained for various oxidation temperatures and compared with those known from
the literature about calcination of Al
precursors. The aim of this work is to evaluate the use of IR spectroscopy and XPS analysis
to probe the structural varieties of Al
. For this objective, a study of the PM2000 oxidation at various temperatures was conducted
by means of XRD, IR spectroscopy, XPS analysis, EDX analysis, and SEM observations. This allowed us to clearly differentiate the
transition Al
from the 𝛼-Al
, to differentiate the characteristic of the IR spectrum of 𝛾-𝛿
phases from that of the 𝜃 phase.
