<p>A thermoelectric material can be obtained by co-pulverizing and mixing a material containing at least bismuth and a material containing at least tellurium, without being alloyed by melting, and then molding and sintering. This thermoelectric material has high performance and can be utilized in a variety of fields such as thermoelectric power generation and thermoelectric cooling, a temperature sensor, space development, marine development, and electric power generation in the remote areas. Since metal elements are used as a starting material, the starting material can be easily prepared. Moreover, in the production steps, the thermoelectric material can be produced in a high yield at a low energy consumption level by a simplified manner, without a complicated operation or special apparatus, and its production cost can be decreased.</p> |
