Abstract Metastable α-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 α-Fe2O3-SnO2 materials are discussed. Tin ions in α-Fe2O3 are found to occupy the empty octahedral holes in the α-Fe2O3 lattice. This interstitial model can also describe the structure of α-Fe2O3-TiO2solid solutions. Finally, a correlation of gas sensitive properties with microstructure of α-Fe2O3-SnO2 materials is presented.
