Abstract

PURPOSE: To efficiently and industrially produce Cu-Ag two-layer coated powder having superior uniformity and adhesion by chemically plating powder with Cu in a Cu plating soln., adding Ag ions to the plating soln. and chemically plating the Cu coated powder with Ag.
CONSTITUTION: Powder with a noble metal such as Pt captured on the surface by a known method is chemically plated with Cu by immersion in a chemical Cu plating soln. contg. inorg. salts such as copper sulfate as a Cu ion source, an alkali such as NaOH, a complexing agent such as EDTA and a reducing agent such as formaldehyde. Ag ions or Ag complex ions are then added to the plating soln. in the form of an aq. silver nitrate soln., etc., and the Cu coated powder is chemically plated with Ag. Cu-Ag two-layer coated powder having superior uniformity and adhesion is industrially produced.
