Particle size distribution of copper powder
- 39 Downloads
It is demonstrated that the primary particle radius distribution of PM-1 electrolytic copper powder is an exponential one. The particle size distribution of electrolytic copper powders can conveniently be characterized by means of a distribution function of the typef (r)=a exp [−a(r−b)], wherea and b are experimentally determined constants.
The mean radius and distribution variability may be recommended as stable technical characteristics of electrolytic copper powders.
The primary particles of the electrolytic copper powder constitute a system characterized by the “absence of an aftereffect” with relation to their linear dimensions.
