Abstract

Monophase Fe2W and FeMo intermetallics have been prepared by hydrogen reduction of Fe2WO6 and FeMoO4 oxides respectively below 1050 K. The ternary intermetallics Fe2W0.9Mo0.1 and FeMo0.9W0.1 have also been prepared by a similar method from the respective substituted oxides. The oxides and the intermetallics have been characterized by X-ray powder diffraction, X-ray photoelectron and Mossbauer spectroscopies. The observed negative isomer shift of Fe in the intermetallics is attributed to an increase in the electron density in Fe by electron transfer from W or Mo to Fe.
