The pseudobrookite-structure MgTi2O5was successfully synthesized by the aqueous sol-gel method using titanium dioxide and magnesium nitrate as starting materials instead of expensive organic solvent and metal alkoxides. The as-prepared nanopowders were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA) and transmission electron microscope (TEM), respectively. The results showed that the calcinations process of gel consisted of a series of oxidation and combustion reactions, accompanied by significantly exothermal effects. Highly reactive nanosized magnesium titanate powders were successfully obtained at 650 °C with less than ~100 nm.
