Formation of Nickel, Cobalt, Copper, and Iron Aluminates fromα- andγ-Alumina-Supported Oxides: A Comparative Study
The rates of metal aluminate formation inMeOx/Al2O3systems (Me=Ni, Co, Cu, Fe) at 500–1000°C in O2or N2atmospheres were compared, using bothα-Al2O3andγ-Al2O3substrates. Interfacial reaction toMeAl2O4was assessed using Rutherford backscattering spectrometry and X-ray diffraction. The lateral homogene...

Zusammenfassung: | The rates of metal aluminate formation inMeOx/Al2O3systems (Me=Ni, Co, Cu, Fe) at 500–1000°C in O2or N2atmospheres were compared, using bothα-Al2O3andγ-Al2O3substrates. Interfacial reaction toMeAl2O4was assessed using Rutherford backscattering spectrometry and X-ray diffraction. The lateral homogeneity of the samples was investigated using scanning electron microscopy. The spinel formation rate follows the sequence FeAl2O4 |
