| 摘 要： | Ca3Co4O9是一种具有广泛应用前景的热电功能材料，为了提高其热电性能，利用高压成型方法及常规二次固相反应技术，制备了稀土ce掺杂的氧化物热电陶瓷材料ca3-xcexCo4O9（z=0，0．1，0．3，0．5），在室温条件下对其微观结构和热电性能进行了测试分析．经扫描电镜测试发现，高压方法制备样品的致密度较高．热电性质测试表明，Ca3CO4O9的电阻率及See—beck系数随Ce掺杂量（z）的增加而增大，x=0．1时得到最大的功率因子；与常规二次固相反应制备的样品相比，高压制备的样品具有更高的热电性能． |

| Abstract: | Ca3Co4O9 is a kind of thermoelectric material,which can be apptied to practice widely.In this paper,thermoelectric material Ca3Co4O9 was doped with Ce into the composition of CexCa3-xCo4O9(x=0,0.1,0.3,0.5)which were prepared by solid state reaction and high pressure method.The microstructures and thermoelectric properties of the CexCa3-xCo4O9 were investigated in room temperature.The SEM measurement results showed that the samples prepared by higher pressurecould have higher density.The thermoelectric properties measurement showed that the electrical resistivity and Seebeck coefficient of CexCa3-xCo4O9 would increase with the increase of x.The maximum power factor was obtained when x=0.1.High pressure synthetic sample has higher thermoelectric performance than that of the same composition samples prepared by conventional solid state reaction. |
