In our opinion, using micro-sized TiO 2 as starting materials is an efficient way to reduce the preparation cost of Li 4 Ti 5 O 12. After activated by high-energy ball milling, micro-sized TiO 2 has lower degree of crystallinity and smaller particle size, which is beneficial for the synthesis of Li 4 Ti 5 O 12.

BaTiO 3 powders were prepared through mechanical activation chemistry and analyzed by Rietveld refinement with X-ray diffraction data. Raw BaCO 3 and TiO 2 powders were dry milled for 5 and 20 h and then calcinated for 2 and 4 h at 800 °C. The milling process was found to have broken up the BaCO 3 and TiO 2 crystals into smaller crystals and formed only small amounts (<1.5 wt%) of BaTiO 3.
