NTIS: PB 190 479 :11 pages
The electrowinning of beryllium from beryllium oxide (beo) using a molten-salt electrolyte composed of 56 lif-37 bef2-7 beo (mole- percent) was investigated. Anodes made of porous carbon were found to be superior in current-carrying capacity and gave a lower cell voltage than other types of anode material tested. When porous carbon anodes were used, the resultant increase in anode area prevented anode passivation. The cell voltage was 3.3 Volts, and electrode current efficiencies of 50 to 70 percent were obtained. The electrodeposited beryllium was recovered as beryllium powder or was coalesced to metal beads by heating to 1,300 deg. C.
