✦ Synopsis
A furnace was constructed to solder thermoelectric materials at high temperatures in vacuum or a gas atmosphere. Electrical junctions for the hot side of a thermoelectric generator consisting of FeSi2 and higher manganese silicide were developed. Material for the junction is TiSi2 soldered with 'Ti-activated' Ag. Contact resistivity was found to be low compared to the material's resistances and stable against the thermal stress at the working temperature. Electron microscopic investigations did not detect any ageing process. The results support the applicability of the developed contacts in a thermoelectric generator.
