Defect structure of nonstoichiometric perovskite

The Po 2 dependance on electrical conductivity and the oxygen diffusion in non-stoichiometric BaTiO 3 and (Ba, Ca) TiO 3 ceramics were investigated. It is confirmed that the electrical conductivity of A-site-excess specimen at high temperature is decreasing with decrease of oxygen pressure. The mech...

Beschreibung
Zusammenfassung:	The Po 2 dependance on electrical conductivity and the oxygen diffusion in non-stoichiometric BaTiO 3 and (Ba, Ca) TiO 3 ceramics were investigated. It is confirmed that the electrical conductivity of A-site-excess specimen at high temperature is decreasing with decrease of oxygen pressure. The mechanism is discussed with the oxygen defect structure, defect structure, barium titanate, calcium doping, Semi-conductor, nonstoichiometry, electrical conductivity, oxygen diffusivity.
