WebFrom investigations of phase diagrams of ternary oxides the lattice sites of foreign ions and compensating vacancies are established. Large trivalent ions occupy barium sites and are completely compensated by titanium vacancies. Small pentavalent ions occupy titanium sites and are mainly compensated by titanium vacancies. Web17 jan. 2024 · It is expected that if Ba 2+ ion is replaced by ions of smaller size, the motion of the Ti 4+ ion on the octahedral site will be reduced. The ionic radii of Ba 2+ and Sn 2+ are respectively 146 pm and 118 pm, so if Sn 2+ is used as doping agent, the properties of BaTiO 3 (BT) will be changed.
