Copper chip can not fragmented into powder by using rod milling. In contrast to rod milling, copper chip can be changed into powder by horizontal ball milling for above 36 hours. It was found that recycling of copper chip scraps into copper powder by horizontal ball milling is possible and powder fraction percent ($75{sim}150{mu}m$) of milled ...

The as-received dendritic copper powders change their shape sequentially to flaky, disk-typed particles and finally, to globular type particles. Also, the tendency of globular formation was prominent in the milled Cu-Cu coated MWNTs (multi-walled carbon nanotubes) powder and the grain size of the sintered Cu coated MWNTs specimen decreased more than that of the pure …
