Die Löslichkeit des SbF3 ist außerordentlich groß, es lassen sich Lsgg. von 800 g SbF8 /l entsprechend etwa 545 g Sbfl herstellen. Aus wirtschaftlieben Gründen ist es nicht zweckmäßig, mit reinen Fluoridlsgg. zu arbeiten. Statt freiem H 2 SO. ist auch NaHS04 an Stelle von HF auch NaF zu benutzen. Die Elektrolyse erfolgt in ausgehleiten Gefäßen. Erwärmung ist wegen der damit leicht verbundenen Verluste an HF unerwünscht.
