摘要: Abstract This paper describes the effect of oxygen partial pressure on Nb solubility in polycrystalline BaTiO 3 at 1673 K. It was found that an increase p(O 2 ) gas phase results increased . Annealing , covered with a thin layer NbCl 5 air 1573 K incorporation to level 0.1 at.% while annealing same temperature nitrogen (involving 2% H does not lead into The observed is consistent defect disorder model
