Abstract

Nanostructured, crystalline copper powder was produced at ambient temperature by aqueous reduction of a copper salt by sodium borohydride. Conditions were optimized to produce boron-free copper powder with an average particle diameter of 200 nm, surface area of 5.48 m * m/g, and oxygent content of 0.155%. The effects of different experimental conditions on average particle size of the powder were also studied. The sintering phenomenon exhibited by produced copper particles at 100°C may be attributed to the low oxygen content of the powder along with other size variation-dependent factors.
