Method for introducing new color into a precious metal and a precious metal alloy manufactured by the same

摘要

The present invention relates to a method of spraying new colors onto a precious metal comprising the steps of: preparing precious metal particles with 0.01-50m of the average granularity and one or more kinds of metal oxide particles with 0.01-10m thereof (a); and manufacturing a powder molded body by mixing 1.0-30 parts by weight of the metal oxide particles with the precious metal particles based on 100 parts by weight of the precious metal particles (b), and a precious metal alloy manufactured thereby.
