Method for refining and homogeneously distributing alloying partners and for removing undesirable reaction products and slags in or from soft solder during the production of fine solder powder

Method for refining and homogeneously distributing alloying partners and for removing undesired reaction products such as oxides and/or slag in or from soft solder during the production of fine solder powder, in which the solder alloy is melted in a high temperature-resistant plant and/or animal oil, the melt is moved to another container of oil with a temperature of at least 20° C. greater than the liquidus temperature, stirred there, and subjected to multiple shear treatments using rotors and stators for forming a dispersion comprising solder balls and oil, from which dispersion the solder balls are separated by means of subsequent sedimentation.
