METHOD OF PRODUCING THERMOELECTRIC SEMICONDUCTOR ALLOY, THERMOELECTRIC CONVERSION MODULE, AND THERMOELECTRIC POWER GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high-performance thermoelectric conversion module, a high-performance thermoelectric power generation device, and a method of producing a half Heusler alloy for constituting them.;SOLUTION: A half Heusler alloy is represented by a formula A_3-xB_XC (wherein A and B are respectively at least one member selected from transition metals consisting of Fe, Co, Ni, Ti, V, Cr, Zr, Hf, Nb, Mo, Ta and W, and C is at least one member selected from Group 13 or 14 elements consisting of Al, Ga, In, Si, Ge and Sn). A method of producing the half Heusler alloy is characterized in that a molten alloy is rapidly-solidified at a cooling rate of 1×10² to 1×10³°C/s.;COPYRIGHT: (C)2006,JPO&NCIPI
