Abstract

A sintered thermocouple limb comprises a thermoselectrically active substance such as compounds of elements of the IVth, Vth and VIth groups of the Periodic system, e.g. Bi2Te3 or Sb2Te3/Bi2Te3, with the contact faces coated with a sintered layer of a mell solderable material such as Al, Si, Cu, Mn, Fe, Co, Ni, Zn, Ge, Ag, Cd, In, Sn, Sb, Te, Au, Tl, Pb, Bi or the Pt group elements so that an intermediate electrically barrier free diffusion layer is formed. The intermediate layer may also be formed by a metallic layer of one of the above elements introduced between the solderable layer and the thermoelectrically active material. Separate layers of the respective powdered materials are charged into a die pressed and sintered at 380 DEG C. in hydrogen. The sintered compact may be further cold-pressed or hot-pressed at 450 DEG C. Alternatively the cold-pressed "green" compact may be directly hot-pressed.
