The release of oxygen during the sintering of Sb 2 O 3 ‐doped BaTiO 3 ceramics containing excess TiO 2 was measured using a mass spectrometer. The amount of oxygen released is proportional to the dopant concentration in the product phase. The evolution of oxygen during sintering was attributed to dissolution of the oxidized form of doped BaTiO 3 in the reacting mixture and simultaneous re‐crystallization of the‐ reduced form.
