Synthesis of pure, homogenous Zn(4)Sb(3)

In the present result we have developed a new route for synthesis of very high purity, single phase Zn(4)Sb(3). This material fills the gap in the intermediate temperature range (100-500 degrees Celsius), where there are no other materials with an adequate figure of merit. Conventional synthesis procedures have problems with phase purity, and therefore with adequate optimisation of thermoelectric performance. The application in the intermediate temperature range offers opportunities for economic recovery of waste or low-grade heat in several applications to increase the overall operation economy. Waste heat recovery can contribute to an increase of the total operation economic effectiveness of some 3-5%. Within vehicles there are several application for the conversion of heat to electric current; e.g. from car exhaust gases and breaks. The recovered electrical energy can thus be recycled.

With the increased demand on clean air of European Cities, electrical cars, or hybrid cars containing electrical motors are becoming a reality. Electrical recovery of heat emitted from the breaks can be most efficiently recovered through TE conversion. This technology is also suitable for other electrically driven crafts, such as trains, tramways, etc. General Electric in the USA has tested proto-type models for car breaks. Only in this sector, there are several billions euros worth of products per year.
