Beryllium was successfully electrorefined in a fused salt cell with an inert gas atmosphere and a graphite liner at 450 or 550 deg C. The fused salt was a LiCl--KCl eutectic to which BeCl/sub 2/ was added. The depositing cathode was an iron rod and the anode was an iron basket containing crude beryllium metal. After deposition, the cathode deposit was cooled and stripped from the cathode, leached in dilute HNO/sub 3/, washed, and dried. Analyses of the dried deposits showed that all the impurity elements except C were reduced; Mg, Ni, Al, and Cr were reduced to negligible contents, whereas O, Si, Fe, and N were appreciably reduced; but Mu and Cu were not removed to a large extent. The purity compares favorably with that of high-purity beryllium prepared in other ways. (D.L.C.)
