ABSTRACT:
A process for producing a thermoelectric material comprises molding a material powder comprising two or more elements selected from the group consisting of bismuth, tellurium, antimony and selenium and having average diameter in the range from 0.05 to 100 .mu.m and sintering the molded material powder with or without hot isostatic pressing. The material powder may be calcinated before the molding. A process for producing a thermoelectric element comprises cutting out pieces of a pillar-like shape from each of a p-type thermoelectric material and a n-type thermoelectric material, connecting the pieces cut out from the p-type thermoelectric material and the pieces cut out from the n-type thermoelectric material alternately with electrodes at the upper faces or the lower faces of the pieces and attaching insulating base plates to the surfaces of the electrodes. The p-type thermoelectric material and the n-type thermoelectric material are respectively produced by the process described above. The thermoelectric element has improved thermoelectric property, excellent stability of the thermoelectric property and excellent mechanical strength.
