ABSTRACT:
Metal copper powder having excellent dispersibility and small particle diameter deviation is manufactured by adding a reducing agent into a solution containing a copper compound and a dispersion agent to precipitate metal copper powder. The solution may further include ammonia so that copper ammonia complex ions exist in the solution. The dispersion agent is either a phosphate such as pyrophosphate, tripolyphosphate, tetrapolyphosphate, metaphosphate and hexametaphosphate or a water-soluble polymer such as naphthalenesulfonate formaldehyde polycondensate, polyvinyl alcohol, carboxymethylcellulose salts, arabic gum, adipate and polycarboxylate.
