Ca3Co4O9+δCe掺杂微观结构磁性曲线Ca3Co4O9+δ Ce-Doped Microstructure Magnetic Curve


本文应用溶胶-凝胶法制备热电材料Ca3Co4O9+δ(x = 0, 0.05, 0.10, 0.15)粉体。研究Ce掺杂对粉体微观结构的影响。XRD结果表明,随着Ce掺杂含量增加,衍射峰向大角度偏移,说明了Ce元素通过掺杂到Ca3Co4O9+δ晶格当中。通过SEM扫描发现,材料的晶粒呈层状结构且尺寸大小均匀。通过振动样品强磁计(VSM)对样品磁性进行分析,发现Ce元素的掺杂对样品的磁性有轻微的影响。

This thesis is to produce thermoelectric material powders Ca3Co4O9+δ(x = 0, 0.05, 0.10, 0.15) in application of sol-gel method. It also studies Ce doping’s effects on powder microstructure. XRD results show that as the Ce doping content increases diffraction peak shifts to a large angle, which indicates Ce element is doped into the Ca3Co4O9+δ lattice. Through SEM scanning, we can find that the grains of the material are layer-structured and in a uniform size. Through the analysis for sample magnetism by VSM vibration, we can find that Ce doping has an effect on sample magnetism.
