Abstract
A p-type thermoelectric material is prepared by mixing and melting at least two members selected from bismuth, tellurium, selenium, antimony, and sulfur to obtain an alloy ingot, grinding the alloy ingot to obtain powder of the allow mass; and hot pressing the powder. At least the hot pressing is carried out in the presence of any one of hexane and solvents represented by CnH2n+1OH or CnH2n+2CO (where n is 1, 2 or 3). A dopant may be used at the step of mixing.
