Abstract

A thermoelectric device (1), and a method for manufacturing said device (1), intended for high-temperature applications for converting heat to electricity by means of the Seebeck effect. The device (1) consists of a green body sintered in protective atmosphere, which in turn consists of a body (12) of hardened ceramic material with thermoelectric couples (10) embedded therein. The ceramic material of the body shows a significantly increased porosity, which has been obtained by means of pore-forming means, preferably microballoons or microspheres (13), admixed to the ceramic material. Conduction paths (16) for connection of the thermoelectric couples (10) consist of thermally sprayed, electrically conductive contact material. This contact material is sprayed onto the end surfaces of the couples (10) and onto surfaces of the body (12) which are positioned between the thermoelectric couples (10) that are to be connected.
