A method is provided for producing a thermoelectric object for a thermoelectric conversion device in which a powder having a bulk density ds and elements in the ratio of a Half-Heusler alloy with a theoretical density di is provided. The powder is mechanically compressed and a green body with a tap density dK is formed, the tap density dK being up to 30% of the theoretical density di greater than the bulk density ds of the powder. The green body with the tap density dK is sintered at a temperature of 1000° C. to 1500° C. for 0.5 h to 100 h, a thermoelectric object with a density ds of greater that 95% and preferably 99% of the theoretical density di being produced. |
