Component of Cu/n-SiO2 Composite Particles by Mechanical Milling
Copper based composite powders with nano-SiO2 were prepared by mechanical milling technology. The effects of milling time on morphology and component of the composite particles were characterized by scanning electron microscopy (SEM) and energy disperse X-ray spectroscopy (EDS), respectively. Results showed that dendrite composite particles change to the flaky, and then to spherical ones with the milling time increasing. The n-SiO2 particles disperse more homogeneously in the composite particles with the milling time increasing.
