昭和电工日前开发成功了耐热温度达+700℃的热电半导体材料。这是一种名为方钴矿(Skutterudite)的La-Fe-Sb类材料。计划2008年开始使用这种材料量产热电转换模块,2010年预计销售额可达20亿日元(约合人民币1.5亿元)。使用温度范围为+300℃～+600℃,设想利用汽车尾气和工厂废热进行发电。首次公开此次的研究成果,目的在于开拓汽车和工厂以外的用途。表示热电半导体材料特性指数(ZT)没有公开。不过,根据一年前的试验结果+500℃时为1。目前可能已经改善到接近
Showa Denko recently developed a heat-resistant temperature up to +700 ℃ thermoelectric semiconductor materials. This is a Skutterudite La-Fe-Sb based material. It is planned to begin production of thermoelectric conversion modules using this material in 2008, and the estimated sales in 2010 will reach 2 billion yen (about 150 million yuan). Operating temperature range +300 ℃ ~ +600 ℃, envisaged the use of automotive exhaust and plant waste heat for power generation. The first public disclosure of the research results, aimed at developing automotive and other uses outside the factory. Indicates that the thermoelectric semiconductor material property index (ZT) is not disclosed. However, according to the test result of a year ago + 1 at 500 ℃. It may have improved to be close now
