Monoclinic Li 2 TiO 3 phase is prepared from Li 2 CO 3 and TiO 2 mixtures by using a high-energy ball milling method, combined with subsequent calcinations at low temperature. Pure phase Li 2 TiO 3 nanopowders with the average particle size of 36.8 nm are obtained from the precursor milled for 20 h and calcined at 500°C for 5 h, i.e., 300°C lower than required by a conventional solid state reaction process or chemical routes. It is suggested that high-energy ball-milling method is a simple and practical route to synthesize Li 2 TiO 3 nanopowders.
