The method and apparatus for removing substantially all oxygen from an electrolytic melt of a fluoride of alkali metal fluorides or alkalide earth metal fluorides is improved by using a hollow carbon anode. The melt is maintained above its melting temperature, the hollow carbon anode is immersed in the melt, an ambient pressure is maintained on the melt which is less than one-third the pressure within the hollow anode and a positive potential is maintained on the anode relative to the melt which is sufficient to remove oxygen but less than the potential at which anode effect occurs.
