The experimental studies on fabrication methods of a lithium lead alloy (Pb-Li) and desorption of non-metal impurities dissolved in the alloys were carried out. The alloys having various Li concentrations were fabricated from small metal grains of Pb and Li. The desorption behavior of gases dissoved in Pb, Pb-Bi and Pb-Li was investigated by the temperature programmed desorption (TPD) analysis. Pb and Pb-Bi contained H2O and CO2, and these chemical compounds were desorbed from the alloys below 700K. Desorption of H2 from Pb-17Li was detected. These behaviors were based on their thermodynamic stability in the alloys. It was found that the non-metal impurities in the alloys could be removed by the TPD method.
