铍因其对热中子的低吸收和高散射截面而受到原子能领域的关注。本文综述了该金属的冶金性能及其在核领域的应用。研究了铍化合物溶液在有机溶剂和液态氨中的电解沉积。在完成本研究之前立即发表的最新工作4中，在乙醚中电解含有二甲基铍和氯化醚铍的溶液时，获得了纯度高达95%的连贯铍沉积物。用这种方法得到的镀层优于用2.8 M的BeCl2.2(C2H5)2O溶液在乙醚中电解得到的粉末镀层。虽然制造铍的商业方法之一涉及高温电解氯化铍5，但在碱卤化物熔体中通过阳极溶解和阴极沉积回收和电精炼废金属的可能性很少受到重视。
BERYLLIUM is of interest in the atomic energy field because of its low absorption and high scattering cross-section for thermal neutrons. The metallurgical properties and nuclear applications of the metal have been reviewed recently1. The electrolytic deposition of beryllium from solutions of beryllium compounds in organic solvents2 and in liquid ammonia3 has been studied. In the most recent work4, published immediately before completion of the present investigation, coherent deposits of beryllium of up to 95 per cent purity were obtained during the electrolysis of a solution containing dimethyl beryllium and beryllium chloride etherate in ethyl ether. Deposits obtained from this bath were superior to the powdery deposits obtained by electrolysis of a 2.8 M solution of BeCl2.2(C2H5)2O in ethyl ether. Although one of the commercial methods of manufacturing beryllium involves the high-temperature electrolysis of beryllium chloride5, in alkali halide melts the possibility of recovery and electro-refining of scrap metal by anodic dissolution and cathodic deposition has received little attention.
