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 ...

The effect of the particle shape and structure on the flowability of electrolytic copper powder. I. Modeling of a representative powder particle [PDF]

Journal of the Serbian Chemical Society, 2003
One of the most important properties of copper powder is its flowability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting the free flow of copper powder

The critical apparent density for the free flow of copper powder [PDF]

Journal of the Serbian Chemical Society, 2003
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 exhibit free flow.

The effect of the particle shape and structure on the flowability of electrolytic copper powder. II. The experimental verification of the model of the representative powder particle [PDF]

Journal of the Serbian Chemical Society, 2003
An analysis of the effects of the shape, surface structure and size distribution of particles on the flowability of the copper powder was performed. It is shown that the most important property of the particles of a powder, regarding the flowability of ...

Physical modelling of representative particles of electrodeposited copper powders [PDF]

Journal of the Serbian Chemical Society, 2006
A method for the estimation of the size of the representative particle of a copper powder is given. Cross sections of representative particles of flowing and non-flowing powders estimated by this procedure are also presented.
