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.

A precise and rapid method for the volumetric assay of uranium metal has been developed. The method consists of dissolving a weighed sample in an aqueous mixture of hydrochloric, sulfuric, and fluosilicic acids. The resulting uranium solution is titrated without a subsequent reduction step.
