A simple oxidation route to prepare pseudobrookite from Panzhihua raw ilmenite was developed. By oxidizing ilmenite concentrate in air for 3 h at 1473 K, a pure pseudobrookite was achieved. The X-ray diffraction studies showed a possible sequence of the phase evolution with temperature, FeTiO(3)-> FeTiO(3)+Fe(2)O(3)+TiO(2)-> Fe(2)O(3)+TiO(2)+Fe(2)Ti(3)O(9)-> Fe(2)O(3)+TiO(2)+Fe(2)TiO(5)-> Fe(2)TiO(5). The sluggish formation reaction of the target product was ascribed to the low heat treatment temperature. During the phase transformation, the extra Ti atoms from FeTiO(3) accommodate into the 4c and 8f sites to form the solid solution (Fe,Ti)(2)TiO(5). AC susceptibility determinations indicated that the as-prepared pseudobrookite was an antiferromagnetic compound and performed the typical anisotropic spin glass behaviors. The decreased phase transition temperature of the prepared pseudobrookite from order to disorder meant a high disorder degree. This oxidation route might be useful to the comprehensive utilization of raw ilmenite, especially for Panzhihua ilmenite in Pan-Xi region of China.
