摘　　要：热电材料是一种直接将热能和电能进行相互转换的能源材料,在废热(余热)发电、太阳能热源发电等方面有广阔的应用前景.氧化物热电材料具有性能稳定、可在高温环境下长期工作、无污染及成本低廉等优点,已成为高温热电转换材料领域研究的热点之一.系统阐述了氧化物热电材料的研究现状,讨论了结构调控技术提高材料热电性能的原因,并提出了氧化物热电材料的发展方向.Thermoelectric power generation as a promising energy conversion technology that is not harmful to the environment has recently attracted renewed interest. Metal oxides ,due to their high stability at high temperature, easy manufcture and low cost,have been drawing more and more attention as new high temperature thermoelectric materials. This paper reviews the current aspects of oxide thermoelectric materials, and some strategies for reducing the lattice thermal conductivity in bulk ox- ide cera＇n, ies so as to enhance thermoelectric performance also are discussed.
