About the stabilization of the dendritic structure of GG brand copper powder

open access: yesChimica Techno Acta, 2015
In industry copper powder is recieved under constant DC. Surface roughening occurs during evolution of the dendritic particles. It is suggested to create a new impulse of current equal to the initial current density of 3200 A/m2 in order to obtain ...
