  • Publication number: 20110236565
    Abstract: An electroless palladium plating solution includes a polar solvent, at least one palladium salt, at least one non-nitrogenated complexing agent, an alkaline adjusting agent that adjusts the plating solution to a pH of at least 8.0, and a reducing agent. The plating solution, which is used for forming a layer of palladium on a surface of a substrate, yields a substantially pure palladium deposit on the substrate. Precipitation of reduced palladium in the plating solution is substantially prevented.

  • Publication number: 20030201040
    Abstract: A method is provided for producing metallic platelets. By determining the ratio of the diameter of the metal source to the thickness of the metallic platelet and the workability of the metal source, a high quality metallic platelet can be developed. According to this method, the platelets that are produced can be used in such applications as building and construction materials for improved weather-resistance, heat-reflection/management, anti-fouling resistance and architectural appearance.
