Description
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 deg. C to 130 deg. 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
