摘要
从结构、制备和掺杂改性3个方面论述了氧化物热电材料Ca_3Co_4O_9的研究状况,并简短总结了Ca_3Co_4O_9热电材料的Ca位或Co位掺杂效果,发现Co位掺杂效果不如Ca位掺杂效果明显,指出适当掺杂的Ca_3Co_4O_9是目前最具中高温应用前景的热电材料之一。
The research status of oxide thermoelectric material Ca3 C04 O9 is reviewed from the structure, preparation and doping. The effects of Ca-site and Co-site doping in Ca3 C04 09 are briefly summarized. It is found that the effect of the Ca-site doping is much apparent than that of the Co-site doping. The results suggest that the Ca3Co409 with appropriate doping will be one of thermoelectric materials with the most applicable prospect in moderate and high temperatures.
