Abstract: The effects of B₂O₃ vapor doping on the dielectric properties of barium titanate ceramics were studied. After the doping, the Curie point of BaTiO₃ ceramics was increased from 128 °C to 130 °C and the maximum dielectric constant was considerably increased. X-ray diffraction showed that both the grain lattice parameters and the tetragonality were increased by the boron oxide vapor doping. It was proposed that boron interstitial was introduced into the grain lattice of barium titanate ceramics by B₂O₃ vapor doping and the dielectric properties were thus obviously changed.
