Abstract
This paper describes the effect of oxygen partial pressure on Nb solubility in polycrystalline BaTiO3 at 1673 K. It was found that an increase of p(O-2) in the gas phase results in an increased Nb solubility in BaTiO3. Annealing of polycrystalline BaTiO3, covered with a thin layer of NbCl5, in air at 1573 K results in Nb incorporation to the level of 0.1 at.% while annealing at the same temperature in nitrogen (involving 2% H-2) does not lead to Nb incorporation into BaTiO3. The observed effect of p(O-2) on Nb solubility in BaTiO3 is consistent with the defect disorder model of BaTiO3.
