    摘要: Cyanide-free acidic silver electroplating compositions include one or more acids or salts of tellurium and may be used to electroplate matte silver deposits on metals, such as nickel, copper or copper alloys. Matte silver metal may be electroplated at conventional plating rates or at high plating rates, such as in reel-to-reel and jet plating. The cyanide-free acidic silver electroplating compositions may be used to electroplate matte silver in the manufacture of electronic components such as electrical connectors, finishing layers for metallic substrates, optical devices and decorative applications.
