Beryllium bars obtained by fusion under ultravacuum by electron bombardment of foils of electrolytic Be were then purified by floating zone fusion under Ar. Three electrolytic fused salt melts were used. The impurities in the foils from the three melts were determined and compared, and a melt of KCl, LiCl, and BeCl/sub 2/ gave a slightly superior quality of Be with respect to the concentration of Fe, Mn, and Ni. The floating zone fusion process gives Be bars, after the third pass, that can be bent easily by hand at room temperature, regardless of the quality of the starting material. The impurity concentrations are tabulated. The evolution of the resistivity at room temperature with respect to the resistivity at the temperature of liquid hydrogen is shown. (J.S.R.)
