THERMOELECTRIC CONVERSION MATERIAL AND THERMOELECTRIC CONVERSION MODULE USING THE SAME |
| 摘要 |
The present invention provides a thermoelectric conversion material that is a material comprising elements less poisonous than Te and has a Seebeck coefficient comparable to BiTe. The present invention is a full-Heusler alloy that is represented by the composition formula Fe2+σTi1+ySi1+z and has σ, y, and z allowing the material to fall within the region surrounded by (Fe, Ti, Si)=(50, 37, 13), (50, 14, 36), (45, 30, 25), (39.5, 25, 35.5), (54, 21, 25), and (55.5, 25, 19.5) by at % in an Fe—Ti—Si ternary alloy phase diagram. |

1. A thermoelectric conversion material wherein said thermoelectric conversion material is a full-Heusler alloy, is represented by the composition formula Fe2+σTi1+ySi1+z, and has σ, y, and z allowing the material to fall within the region surrounded by (Fe, Ti, Si)=(50, 37, 13), (50, 14, 36), (45, 30, 25), (39.5, 25, 35.5), (54, 21, 25), and (55.5, 25, 19.5) {excluding (50, 25, 25)} by at % in an Fe—Ti—Si ternary alloy phase diagram. |
