The synthesis of nanosized titanium oxides from nitrate melts is proposed, and possible mechanism of this process is discussed. As shown, the NH4F.HF additives affect the oxidation of titanium powder in molten nitrates. Using small amount of NH4F.HF, the mixture of polytitanates having ‘1???D’ morphology is synthesized. Some oxide powders with crystal sizes of 30–50 nm show evidence of electrochemical activity.
