Refining Lithium by Vaporization at Low Pressure

CIM Bulletin, 1951

The experiments described demonstrate that crude commercial lithium containing in the order of 0.5 per cent sodium can be refined, the resulting metal containing as low as 0.001 per cent sodium. During the process, the metal is vaporized and condensed at a gauge pressure of Jess than 0.04 micron. Considerable operating data and a detailed description of the experimental equipment are included.
