Abstract

The FeTi intermetallic compound, when oxidised at various temperatures, exhibits some interesting properties. XRD analysis of the treated samples indicates the formation of FeTi03 and Fe304 phases at 973 K. ESR and DRS studies on the alloy sample treated at various temperatures in oxygen revealed that in the case of Ti, oxidation proceeds in a step-wise process forming the oxygen deficient phase and then the Ti02 phase, which ultimately leads to the ternary FeTi03 phase. Iron first forms the ferric oxide phase which is then converted to the FeTi03 or the magnetic Fe304 phase. Thus there is evidence for preferential oxidation of the two constituent elements leading to new catalytic systems.
