Claims

1. A PROCESS FOR FORMING IN ONE STEP A THERMOELECTRIC ELEMENT WITH A METALLIC ELECTRICAL CONTACT AT ONE END THEREOF WHICH COMPRISES, CNSOLIDATING, WITHIN A DIE CAVITY, A MASS OF PARTICLES CONSISTING EXCLUSIVELY OF AT LEAST ONE THERMOELECTRIC COMPOSITION SELECTED FROM THE GROUP CONSISTING OF CADMIUM ANTIMONIDE, INDIUM ANTIMONIDE, INDIUM ARSENIDE, GERMANIUM TELLURIDE, BISMUTH SELENIDE, BISMUTH ANTIMONY TELLURIDE, LANTHANUM BARIUM TITANIUM OXIDE, GERMANIUM ANTIMONY TELLURIDE, SODIUM MANGANESE TELLURIDE, MANGANESE GERMANIUM TELLURIDE AND MIXTURES THEREOF, UNDER A PRESSURE OF FROM 1000 TO 15000 P.S.I. WHILE HEATED TO A TEMPERATURE OF FROM 20*C. TO 100*C. BELOW THE MELTING POINT OF THE COMPOSITION, WITHOUT THE USE OF ANY BONDING MATERIAL, WHILE IN CONTACT WITH A METAL ELECTRICAL CONTACT PLATE AT AT LEAST ONE END THEREOF TO PRODUCE A COMPACT BODY WITH THE AT LEAST ONE AFORESAID METAL ELECTRICAL CONTACT BONDED AT THE END OF THE BODY.
