Abstract: The invention relates to a noble metal preparation for producing noble metal decorations on decoratively fireable substrates by direct printing and indirect printing (transfer technique). The printing quality of the preparation containing noble metal compounds and a binder system can be improved in that the binder system comprises a resin mixture of a) 25 to 40 wt. % of polyamide resins, b) 5 to 30 wt. % of sulfurised recent resins, c) 20 to 55 wt. % of rosin-modified resins, d) 0 to 30 wt. % of alkylphenol resins and e) 0 to 30 wt. % of other resins compatible therewith or of the reaction products, formed at 50 to 150° C., of the resin mixture mentioned and/or the reaction products, formed at 50 to 150° C., of the resin mixture mentioned or the reaction products of same containing the noble metal compounds in the presence of a sulfur-containing gelling agent.

Abstract: This invention relates to metal powders. In particular, the invention provides a novel metal-refractory composite powder which will withstand high temperatures, and means for its production. The metals for which the invention will have special application are platinum, palladium, rhodium, ruthenium, iridium, osmium and gold and silver.According to the invention, a metal powder suitable for use at high temperatures comprises an intimate mixture, other than a mere physical admixture, of particles of platinum, palladium, rhodium, ruthenium, iridium, osmium, gold or silver, or an alloy containing one or more of said metals, and particles of a refractory material.

Abstract: This invention relates to metal powders which will withstand high temperatures and which can be used for decorative and catalytic purposes. In more detail, a metal powder in accordance with the invention comprises particles made from a heat resistant substrate individually coated or encapsulated with a layer of platinum, palladium, rhodium, ruthenium, iridium, osmium, gold or silver or an alloy containing at least one of the said metals.
