The effect of Mn doping on the cubic to hexagonal phase transition temperature in BaTiO 3 has been determined by quenching samples with different Mn contents from a range of temperatures. Under conditions of equilibrating samples in air over the range 1000°–1400°C, cubic solid solutions BaTi 1− x Mn x O 3−δ form over the range 0≤ x ≤0.015(5), whereas hexagonal solid solutions form for x ≥0.02, depending on the temperature. The results are compared with those on doping BaTiO 3 with Fe 3+ and observations made concerning acceptor doping with Ti 3+ .
