| 20100051081 | THERMOELECTRIC CONVERSION MATERIAL, METHOD FOR MANUFACTURING THE SAME, AND THERMOELECTRIC CONVERSION ELEMENT - A thermoelectric conversion material is provided which stably exhibits high thermoelectric conversion performance at about 300 to 600° C. and has high physical strength, resistance to weathering, durability, stability, and reliability. A method for manufacturing the same, and a thermoelectric conversion element are also provided. Also provided is a thermoelectric conversion material produced using, as a raw material, silicon sludge which has had to be disposed of in landfill. The thermoelectric conversion material of the invention is characterized by containing, as a main component, a sintered body composed of polycrystalline magnesium silicide containing at least one element selected from As, Sb, P, Al, and B. The manufacturing method uses purified and refined silicon sludge. | 03-04-2010 |
