Abstract
A method for producing a thermoelectric object for a thermoelectric conversion device is provided. A starting material which contains elements in the ratio of a half-Heusler alloy is melted and then cast form an ingot. The ingot is heat-treated for 12 to 24 hours at a temperature of 1000° C. to 1200° C. The homogenised ingot is crushed and ground to provide a powder. The powder is cold-pressed and sintered for 0.5 to 24 hours at a temperature of 1000° C. to 1500° C.
