Abstract
Abstract Metallizations for formation of conductors on substrates, comprising (1) nickel or nickel-containing base metal alloys, and (2) noble metals, e.g., palladium, palladium/gold, platinum/palladium/gold, and palladium/silver, wherein the ratio of nickel or nickel-containing alloy to noble metal is up to 1/1 (by weight). The metallization are used as conductors on ceramic substrates and for ceramic capacitors.
