Abstract
A method for producing a thermoelectric object for a thermoelectric conversion device is provided. A starting material which has elements in the ratio of a half-Heusler alloy is melted and then cooled to form at least one ingot. The ingot is homogenized at a temperature of 1000° C. to 1400° C. for a period of time t, wherein 0.5 h≤t<12 h or 24 h<t<100 h. The homogenized ingot is crushed and ground into a powder. The powder is cold-pressed and sintered at a maximum pressure of 1 MPa for 0.5 to 24 h at a temperature of 1000° C. to 1500° C.
