Method for refining and homogeneously distributing alloying partners and removing unwanted reaction products such as oxides and/or slag in soft solders during the production of fine solder powder comprises using oils as separating medium for separating the melts and the reaction products and/or slag and releasing the slag during melting of the solder, enriching the released reaction products and/or slags in the oil, removing the oil with the reaction products and/or slag, enriching the reaction products and/or slag driven off, mixing the remaining solder melt and removing the enriched reaction products and/or slag together with the oil after sedimentation of the solder balls. |
