先进复合材料结课论文题目：The research progress of oxide thermoelectric materials 姓名： 彭帮强学号： 201512006002日期： 2016年6月25日 Abstract Oxides thermoelectric materials have virtues such as high temperature resistance, anti-oxidation, environment friendly, and the preparation technology is not complicated, do not need to vacuum,which is considered to be one of the most promising thermoelectric materials. Analyzed several typical oxide material crystal structure and thermal performance, and mainly of high temperature oxide thermoelectric materials were reviewed the research progress of preparation, modification methods and application.Key words: oxide thermoelectric material,thermoelectric property一、The realistic significance research of oxide thermoelectric materialsWith the rapid development of national economy, energy shortage and environment pollution problem increasingly prominent, thermoelectric materials due to the energy recycling and the special function of environmental protection, has become the hotspot in the field of material research. In fact, thermoelectric materials have been widely used in navigation, remote space over a long distance detection, waste heat power generation, thermoelectric refrigeration, space exploration, infrared stealth, etc. But, at present the technology is relatively mature, the performance good thermoelectric materials for metal semiconductor alloy, they have high thermoelectric conversion efficiency, but at high temperature is not stable, easy oxidation, and most of the heavy metal containing harmful to human body. By contrast, the oxide thermoelectric materials with excellent structural stability and chemical stability, can under the high temperature oxidation resistance, long service life, safe and non-toxic, simple preparation, high temperature is considered to be a condition has potential application prospects of the new thermoelectric conversion material.二、Main kinds of oxides thermoelectric materials1、Na-Co-O thermoelectric materialsCo
