Abstract:
(EN) The invention relates to a metal paste, containing (A) 75 to 90% by weight of copper and/or silver particles that are provided with a coating containing at least one organic compound, (B) 5 to 20% by weight of an organic solvent, and (C) 2 to 20% by weight of at least one type of metal particles different from the particles of (A) and having an average particle size (d50) in the range of 0.2 to 10 µm. The metal particles of component (C) are selected from the group consisting of molybdenum particles and nickel core-silver shell particles with a silver content of 10 to 90% by weight.
(FR) Pâte de métal contenant : (A) de 75 à 90 % en poids de particules de cuivre et/ou d’argent qui présentent un revêtement qui contient au moins un composé oragnique ; (B) de 5 à 20 % en poids de solvant organique ; (C) de 2 à 20 % en poids d’au moins un type de particules métalliques qui sont différentes des particules (A) et ont une granulométrie moyenne (d50) de 0,2 à 10 µm, les particules métalliques du constituant (C) étant choisies dans le groupe qui contient des particules de molybdène et des particules à noyaux de nickel et enveloppe d’argent ayant une teneur en argent de 10 à 90 % en poids.
(DE) Metallpaste, die (A) 75 bis 90 Gew.-% Kupfer- und/oder Silberpartikel, die ein Coating aufweisen, das wenigstens eine organische Verbindung enthält, (B) 5 bis 20 Gew.-% organisches Lösemittel, und (C) 2 bis 20 Gew.-% mindestens einer Art von von Partikeln (A) verschiedenen Metallpartikeln mit einer mittleren Teilchengröße (d50) im Bereich von 0,2 bis 10 µm enthält, wobei die Metallpartikel der Komponente (C) ausgewählt sind aus der aus Molybdänpartikeln und Nickelkern-Silbermantel-Partikeln mit einem Silbergehalt von 10 bis 90 Gew.-% bestehenden Gruppe.
