通过在一定温度范围内淬火不同Mn含量的样品，测定了Mn掺杂对BaTiO3中立方到六方相变温度的影响。在1000°-1400°C的空气平衡条件下，在0≤x≤0.015(5)范围内形成立方固溶体BaTi1−xMnxO3−δ，而在x≥0.02范围内形成六边形固溶体，具体取决于温度。结果与BaTiO3掺杂Fe3+的结果以及受体掺杂Ti3+的观察结果进行了比较。
The effect of Mn doping on the cubic to hexagonal phase transition temperature in BaTiO3 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 BaTi1−xMnxO3−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 BaTiO3 with Fe3+ and observations made concerning acceptor doping with Ti3+.
