N2 - Sonication is used to prepare binary oxide FexOy-TiO2. Under sonication, the reaction of FeCl3 with (i-C3H7O)4Ti takes place successfully. The products are characterized by XRD, Mössbauer, Magnetic, DSC, TEM, SEM, and BET measurements. The results of characterization show that iron oxides in as-prepared samples are all amorphous and that the particles are nanometric. The product of the nonhydrolytic reaction remains amorphous at 773 K, and at higher temperatures the iron ions exist in the form of Fe2TiO5. The mesopores can withstand calcination of 773 K.
