A method of manufacturing metal to glass, metal to metal and metal to ceramic connections to be used in SOFC applications, said connections being produced as a mixture of a base glass powder and a metal oxide powder. As a result, the inherent properties of the glass used in the composite seals may be altered locally in the metal-coating interface by adding e.g. MgO in order to control the viscosity and wetting, and at the same time maintain the bulk properties such as high coefficient of thermal expansion of the basic glass towards the seal components.

La présente invention concerne un procédé de fabrication de connexions entre métal et verre, métal et métal et métal et céramique devant être utilisé dans des applications SOFC, lesdites connexions étant fabriquées sous forme d'un mélange d'une poudre de verre de base et d'une poudre d'oxyde métallique. Il en résulte que les propriétés inhérentes au verre utilisé dans les joints composites peuvent être localement altérées dans l'interface métal-revêtement par ajoût, par exemple, de MgO dans le but de contrôler la viscosité et le mouillage, et dans le même temps de conserver les propriétés générales telles que le coefficient élevé d'expansion thermique du verre de base envers les composants de joint.
