Abstract
Metastable alpha-Fe2O3-MO2 (M: Sn and Ti) solid solutions can be
synthesized by mechanical alloying. The alloy formation,
microstructure, and gas sensitive properties of mechanically
milled alpha-Fe2O3-SnO2 materials are discussed. Tin ions in
alpha-Fe2O3 are found to occupy the empty octahedral holes in the
alpha-Fe2O3 lattice. This interstitial model can also describe the
structure of alpha-Fe2O3-TiO2 solid solutions. Finally, a
correlation of gas sensitive properties with microstructure of
alpha-Fe2O3-SnO2 materials is presented.
