Experiments were conducted to determine the solubility of N and O in Li at 250 to 450 ction prod- C and to determine which of several possible purification methods is most effective in reducing the N and O content of Li. The solubility of N in Li increased from 0.04 wt.% at 250 ction prod- C to 1.31 wt.% at 450 ction prod- C. The solubility of O was found to be 0.010 wt.% at 250 ction prod- C and increased to 0.066 wt.% at 400 ction prod- C. Vacuum distillation, lowtemperature filtration. cold-trapping, and gettering with active metals were investigated as possible purification methods to reduce the N and O content of Li. Of the techniques studied, gettering with active metals was found to be the most effective method of reducing the N concentration, while cold-trapping and low-temperature filtration were most effective in reducing the O concentration.
