Preparation and Properties of Dispersed Iron (III) Oxide on Rutile.

Abstract Samples of 5 and 20 mole% α-Fe 2 O 3 supported on rutile TiO 2 were prepared by incipient wetness. A temperature of 390°C was found to be necessary for complete decomposition of the nitrates. Below 400°C there appears to be little evidence for strong interactions between α-Fe 2 O 3 and the support. However, ternary phase formation was observed at elevated temperature. Magnetic properties of bulk and supported α-Fe 2 O 3 are compared and discussed.
