Abstract (en)
[origin: EP1277849A1] Flux salt composition contains zinc chloride, alkali metal chloride, one or more alkalizing components and one or more components which oxidize iron (II) to iron (III). An Independent claim is also included for a process for operating a flux bath. Preferred Features: The composition contains 25-70, especially 50-70 wt.% zinc chloride, and 20-90, especially 30-50 wt.% alkali metal chloride. The alkali metal chloride is ammonium chloride. The alkalizing component is zinc oxide, lithium, sodium and/or potassium hydroxide, or zinc carbonate. The oxidizing component is potassium permanganate, zinc peroxide and/or zinc chlorate.
