 note = {The chemical behaviors of non-metal impurities such as O2, H2, N2, H2O, CO2 and CO in lead (Pb) metal,
lead-bismuth (Pb-Bi) alloy and lead-lithium (Pb-Li) alloys were experimentally investigated by means of temperature
programmed desorption mass spectrometer (TPD-MS) analysis. Desorption of H2O and CO2 from the
Pb metal and the Pb-Bi alloy was clearly detected by TPD-MS analysis. However, desorption of H2O and CO2
from the Pb-Li alloys was much less than that from the Pb metal and the Pb-Bi alloy, since these molecules are
chemically unstable and react with Li in the Pb-Li alloys. Then, oxygen and hydrogen must be dissolved in Pb-Li
alloys as they form the chemical compounds of Li (i.e., Li2O, LiOH and LiH). Large desorption of hydrogen from
solid Pb-Li alloys by their heating was detected. The possible mechanism for the large desorption of hydrogen
from the Pb-Li alloys is based on the decomposition of LiH and Pb-Li-H at high temperature. The chemical
behaviors of the non-metal impurities in the Pb-Li alloys was modeled based on the thermodynamic stability.
The methodologies for the fabrication of high-purity Pb-Li alloys and the control of the impurity condition are
discussed.},
