Characterization of the Native Oxide Shell of Copper Metal Powder Spherical Particles
SSRN Electronic Journal, 2022 The native oxide layer that forms on copper (Cu) metal spherical particle surfaces under ambient handling conditions has been shown to have a significant effect on sintering behavior during microwave heating in a previous study, where an abnormal expansion was observed and characterized during sintering of Cu compacts using reducing gases.

Effect of Particle Size Distribution on Laser Powder Bed Fusion Manufacturability of Copper [PDF]
BHM Berg- und Hüttenmännische Monatshefte, 2021 AbstractOne of the major benefits of the Laser Powder Bed Fusion (LPBF) technology is the possibility of fabrication of complex geometries and features in only one-step of production. In the case of heat exchangers in particular, this is very convenient for the fabrication of conformal cooling channels which can improve the performance of the heat ...

The effect of the particle shape and structure on the flowability of electrolytic copper powder IV: The internal structure of the powder particles [PDF]
Journal of the Serbian Chemical Society, 2004 The structure of powder particleswas analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, which does not allow the particles to jam and hence permits the free flow of nonsieved powder.
