A Simple Method to Synthesize Nanosized Li₂TiO₃ Powders Through High-Energy Ball-Milling

Abstract

Monoclinic Li₂TiO₃ phase is prepared from Li₂CO₃ and TiO₂ mixtures by using a high-energy ball milling method, combined with subsequent calcinations at low temperature. Pure phase Li₂TiO₃ 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 Li₂TiO₃ nanopowders.
