The effect of boron vapor doping on the lattice structure of barium titanate-based ceramics was investigated by X-ray diffraction. Both the un-doped and boron vapor doped BaTiO3 ceramics were found to exhibit a tetragonal phase, but the lattice parameters of the doped ceramics are larger than the parameters of the undoped one. This lattice expansion due to the vapor doping is convincing evidence that vapor doping can effectively modify the lattice structure of ceramics. The influence of boron vapor doping on the electrical properties of a barium titanate-based semiconductor was also reported.
