摘　　要：本文研究了掺杂过渡金属氧化物(NiO、CuO、V_2O_5、MnO)对Ce_(0.8)Sm_(0.2)O_(1.9)(SDC)材料烧结行为、力学和热学性能的影响。结果表明:掺杂过渡金属离子可以在不同程度上促进SDC电解质材料的烧结,提高SDC电解质材料力学性能,但对材料热膨胀系数的影响相对较小。其中,NiO、CuO对SDC材料烧结行为和力学性能的影响较为显著。The Effects of doped transition metal oxides(NiO,CuO,V2O5 and MnO)on sintering,mechanical and thermal properties of Sm-doped ceria(SDC)materials were investigated.The results shown that transition metal ions have different promoting effects on the sintering and mechanical properties of SDC materials,and have slight effect on the thermal expansion coefficient.Specially,the remarkable improvements in sintering and mechanical properties were observed when doping NiO or CuO in SDC materials.
