| 摘 要： | 施主含量不同的 BaTiO_3陶瓷在 H_2气氛中烧结后具有相近的平均晶粒直径。在大气中氧化后,它们仍然具有典型的 U 形电阻率～施主掺杂浓度曲线。这与传统理论不完全一致。本文就晶粒尺寸随氧分压的变化关系提出了新的见解。

| Abstract: | After sintering in H_2 atmosphere,BaTiO_3 ceramics with different donor content have got similar grain size.They still have U-type resistivity-donor content curveafter oxidizing in air.Those mentioned above are different from the traditionaltheory.We have proposed our new opinion about the relationship between grainsize and oxygen partial pressure in this paper. |
