Document Type and Number:
Japanese Patent JP7087519
Kind Code:
B2
Abstract:
To provide a thermoelectric device and others which are highly reliable.SOLUTION: First, Ti powder and Al powder are mixed and then, heated in vacuum or an inactive gas, thereby obtaining a Ti-Al alloy sintered body. The Al powder of 8 mass% or more and 36 mass% or less is mixed and heated, whereby a Ti-Al alloyed sintered body can be obtained. The Ti-Al alloyed sintered body thus obtained is pulverized mechanically to obtain Ti-Al alloyed powder (S100). Then, Sb-containing thermoelectric material powder and the Ti-Al alloyed powder are filled in a mold (S101). Subsequently, the thermoelectric material powder and the Ti-Al alloyed powder are pressure-sintered (S102). By doing so, a sintered body in which a thermoelectric material consisting of an Sb-containing alloy and a diffusion-preventing layer 9 formed by a Ti-Al alloy are laminated can be obtained.SELECTED DRAWING: Figure 5
