(EN) METHOD FOR THE COLOURING OF CERAMIC SURFACES
(FR) PROCEDE DE COLORATION DE SURFACES CERAMIQUES
Abstract: front page image
(DE)Die vorliegende Erfindung betrifft ein Verfahren zum Färben von Keramikoberflächen, wobei man die Oberflächen mit einer wäßrigen Lösung eines Alkalimetall- oder Ammoniumdithiosulfatoaurats (I) mit einer Gold-Konzentration von 0,1 - 10 Gewichts-% behandelt, das Wasser verdampft und das Dithiosulfatoaurat (I) bei Temperaturen von 300 - 1400 °C zersetzt.
(EN)The present invention relates to a method for the colouring of ceramic surfaces. According to said method the surfaces are treated with an aqueous solution of an alkali metal or ammonium dithiosulphatoaurates (I) with a gold concentration of 0.1-10 % by weight, the water is evaporated and the dithiosulphatoaurate (I) is decomposed at temperatures of 300-1400 °C.
(FR)L'invention concerne un procédé de coloration de surfaces céramiques, ledit procédé consistant à traiter les surfaces avec une solution aqueuse d'un dithiosulfato-aurate (I) de métal alcalin ou d'ammonium présentant une concentration d'or de 0,1 à 10 % en poids, à faire évaporer l'eau et à décomposer le dithiosulfato-aurate (I) à des températures comprises entre 300 et 1400 °C.
