Inventor: NAKAHARA YASUO
IPC: H01L35/22
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a thermoelectric material whose performance index is high. SOLUTION: Powder of B and row material of BiTe thermoelectric material are mixed, which is sealed up in a vessel (process S10), the mixture sealed up in the vessel is heated to form a mixture molten liquid of a specified composition (process S12), and the mixture molten liquid is cooled while rotated (process S14), to manufacture a thermoelectric material. Since the mixture molten liquid is cooled while shaken, the B particle evenly disperses in a parent material comprising the BiTe thermoelectric material, coming to be a center of scattering. The mixture molten liquid coagulates with no stable liquid surface, suppressing crystal growth of the parent material. As a result, a phonon heat conductivity is reduced, leading to a decreased heat conductivity, so that a thermoelectric material of high performance index is manufactured.
