Abstract

A composite copper coated powder was generated by pressure hydrogen stripping copper from Kelex 100 solvent extractant in the presence of silica powder. Within the limitation of solvent extraction under constant conditions, both loading level and stripping rate were reproducible. The stripping copper kinetics are reduced from a divalent state to a metallic state and then deposited on the surface of the silica powder. Copper nucleates heterogeneously on the seed particles. They are giving an agglomerated and non - uniform powder.

구리입자를 코딩한 분말 합성은 Kelex 100 solvent extraction으로부터 silica powder에 수소압력 stripping copper에 의하여 생성하였다. Solvent extraction의 범위내인 일정한 조건에서 loading level과 stripping rate등을 재생하였으며 stripping copper kinetics는 divalent상태에서 metallic 상태로 감소하면서 silica 입자에 침적하였다. Copper들은 seed 입자에 heterogeneous 핵을 형성하면서 이들은 agglomeration 상태로 생성되었고 불균일한 분말로 형성하였다.
