Process for preparing metal particles.

摘要

Fine particles of a metal such as copper and silver can be obtained by reducing the corresponding metal compound solution with one or more reducing agents selected from the group consisting of L-ascorbic acid, L-ascorbate, D-erythorbic acid and D-erythorbate. Silver-palladium composite particles can also be obtained similarly by employing a colloidal palladium liquid and a silver compound solution.
