X-ray absorption spectroscopy characterization of embedded and extracted nano-oxides
Abstract
Here, the chemistries and structures of both embedded and extracted Ysingle bondTisingle bondO nanometer-scale oxides in a nanostructured ferritic alloy (NFA) were probed by x-ray absorption spectroscopy (XAS). Y2Ti2O7 is the primary embedded phase, while the slightly larger extracted oxides are primarily Y2TiO5. Analysis of the embedded nano-oxides is difficult partly due to the multiple Ti environments associated with different oxides and those still residing in matrix lattice sites. Thus, bulk extraction followed by selective filtration was used to isolate the larger Y2TiO5 oxides for XAS, while the smaller predominant embedded phase Y2Ti2O7 oxides passed through the filters and were analyzed using the log-ratio method.
