Abstract:
A method of producing a sintered body of a material for thermoelectric element, said method comprising the steps of:providing a block of the material for thermoelectric element, said block having an electric-current passing direction, in which electricity is supplied to obtain a desired thermoelectric performance of the thermoelectric element;encasing said block in an elongate capsule such that the electric-current passing direction of said block is substantially agreement with an axial direction of said capsule;degassing said capsule;performing a forming operation for reducing a cross section perpendicular to the axial direction of said capsule to obtain a formed capsule having a green compact of said block crushed by said forming operation therein; performing a heat treatment to sinter said green compact in the formed capsule; andremoving the sintered body from the formed capsule.
