Abstract: L'invention concerne un procédé de production de mélamine consistant à faire réagir de l'urée en présence d'un catalyseur solide dans un réacteur ou plusieurs réacteurs montés en série dans une plage de température allant de 370 °c à 430 °c, à refroidir et à filtrer le gaz formé lors de la réaction de l'urée, à séparer la mélamine par désublimation et à réinjecter dans le ou les réacteurs une partie du gaz présent après séparation de la mélamine ('gaz de recyclage'). Le procédé se caractérise en ce que toutes les étapes susmentionnées sont exécutées sous une pression comprise entre 4 et 10 bars absolus.

Abstract: Dispersion for applying a metal layer on an electrically non-conductive substrate comprises an organic binder component (0.01-30 wt.%); a metal component (30-89.99 wt.%) containing a first metal with a first metal particle (0.01-99.99 wt.%) and a second metal with a second metal particle (99.99-0.01 wt.%); and a solvent component (10-69.99 wt.%); where the first metal and -particle and second metal and -particle are different from each other. Independent claims are included for: (1) a method for preparing the dispersion comprising mixing an organic binder component, a metal component containing a first metal with a first metal particle and a second metal with a second metal particle, a solvent component, dispersing agent, filler components and further components, and dispersing the obtained mixture; (2) preparation of metal layer on at least a part of an electrically non-conductive substrate comprising applying the dispersion on the substrate, drying the dispersion applied layer on the substrate and optionally de-energizing and/or galvanically separating the metal on the dried dispersion layer; and (3) a substrate surface comprising at least a partially electrical conductive metal layer.
