The nano-dispersed barium titanate was synthesised by mechanochemical treatment of barium titanyl oxalate and mixture of BaO and TiO2. Prepared barium titanate demonstrates higher photoactivity in comparison to the same sample obtained by traditional solid state reaction. Shift of absorption edge in the visible region and respective narrowing of the band gap for the milled samples were observed.
