Hello everyone.
I am trying to use ball milling to make small size (200 to 50nm) copper particles. Due to the high ductility of copper small copper particles tend to aggregate and weld together. To imped that I would like to use a process control agent but I don't know what to use. Would starch or cellulose work?
Secondly I'd like to know if using ceramic bowl and balls will only reduce the milling speed compared to hardened steel or if the minimum achievable particle size would also be augmented?
Thank you
Dear Rémi Rafael many thanks for this interesting technical question. In fact, there are reports about the manufacture of very fine copper particles (even nanoparticles) through ball milling in the literature. Please have a look at the following potentially useful article which might help answering your question:

2. The grinding behavior of ground copper powder for Cu/CNT nanocomposite fabrication by using the dry grinding process with a high-speed planetary ball mill

Both articles are freely available as public full texts on RG.
Copper powders can be obtained not only by grinding, but also by electrolytic deposition or electrolytic precipitation with the additional use of ionic liquids.
