Abstract

The hydrothermal crystallisation of barium titanate, BaTiO3, has been studied for the first time by in situ time-resolved neutron powder diffraction; we deduce that BaTiO3 is formed from solution by reaction between [Ti- (OH)x](4−x)+(aq) and [Ba(OH)x](2−x)+(aq) species, rather than by a heterogeneous reaction between solid TiO2 and Ba2+(aq) ions.
