  • Patent number: 11056633
    Abstract: A method can produce a thermoelectric component or at least a semifinished version of the thermoelectric component. The method includes: a) providing a substantially planar substrate; b) providing a pulverulent thermoelectrically active material; c) pressing the active material to form green bodies; d) inserting green bodies into through-holes of the substrate; e) arranging the substrate with the green bodies inserted therein between two substantially planar electrodes; f) contacting face ends of the green bodies with the electrodes; g) exposing the green bodies to an electric current flowing between the electrodes; h) exposing the green bodies to a pressure force acting between the electrodes; i) sintering the green bodies to form thermolegs; and k) levelling the substrate and the thermolegs accommodated therein by bringing them closer to the electrodes while maintaining the parallelity thereof.

  • Patent number: 10308820
    Abstract: A paint system contains an anti-fouling metal oxide and a fumed silica, wherein the fumed silica has a BET surface area of 150 to 400 m2/g, a tamped density of 100 to 300 g/l and a thickening of less than 500 mPas.

  • Publication number: 20170218494
    Abstract: The invention relates to a method for producing a thermoelement for a thermoelectric component, in which method: with the aid of a plasma flame, a diffusion barrier made of nickel is applied to a thermoelectric active material; or, with the aid of a plasma flame, a contact-facilitating layer made of tin is applied to a diffusion barrier made of nickel. The invention also relates to a thermoelectric component comprising thermoelements which are produced correspondingly. The aim of the invention is to further develop the conventional plasma spraying technique such that it can be used to produce thermoelements on an industrial scale. To achieve this aim, nickel particles or tin particles are used, which particles conform to a particular specification with regard to their sphericity.

  • Patent number: 9553249
    Abstract: The invention relates to a method for producing a thermoelectric component or at least one semi-finished product of same, in which a multiplicity of thermolegs made of a thermoelectrically active material are introduced into an essentially planar substrate made of an electrically and thermally insulating substrate material such that the thermolegs extend through the substrate essentially perpendicular to the substrate plane, and in which the active material is provided in pulverulent form, is pressed to give green bodies and is then sintered within the substrate to give thermolegs. It is based on the object of refining the method of the generic type mentioned in the introduction so as to increase the freedom of choice of the thermally and electrically insulating substrate material.
