The continuous production of beryllium metal by low-temperature fused salt electrolysis into a continuously circulating mercury cathode has been demonstrated. The product is amenable to direct hot pressing or to powder preparation by distilling off the mercury. The production of pure beryllium chloride in good yield by direct chlorination of beryllium oxide has also been demonstrated.
