   Es wird daher   nochmals in einen dicht schliessenden Ofen gebracht   und während mehrerer Stunden unter    LuftabschluS8'auf.   helle Rotlglut erhitzt, wobei man in den Ofen 
 EMI2.2 
 Momente der Entschwefelung unter   Luftabschluss befindet.   



   Nunmehr weisen die so erhaltenen Barren neben beträchtlich verringertem Widerstand eine durchaus   gleichmässige   elektromotorische Kraft von 2 bis 8 Zehntel Volt auf, je   nsch der Temperatur,   auf welche man sie erhitzt. 



   Das   Schwofolkupfor   erhält, wie gefunden wurde, durch Zurügung einer bestimmten 
 EMI2.3 
 erzielt ; jedoch   beschränken   sich die Erfinder nicht auf diese Verhältniszahlen.

 gegossene Stücke von Schwefelkupfer der Einwirkung von Schwefeldämpfen unterwerfen und dann bei Luftabschluss geglüht werden, vorzugsweise unter Absorbtion der dabei frei werdenden   Schwofeldümpfo.

   It is therefore once again placed in a tightly sealed oven and kept open for several hours in the absence of air. bright red embers heated, being in the oven
 EMI2.2
 Moments of desulfurization are in the absence of air.



   Now the bars obtained in this way have, in addition to a considerably reduced resistance, a thoroughly uniform electromotive force of 2 to 8 tenths of a volt, depending on the temperature to which they are heated.



   The Schwofolkupfor is obtained, as has been found, by adding a certain
 EMI2.3
 achieved; however, the inventors are not limited to these ratios.



    PATENT CLAIMS:
 EMI2.4
 Cast pieces of copper sulphide are subjected to the action of sulfur vapors and then annealed in the absence of air, preferably with the absorption of the Schwofeldümpfo released in the process.
