New lithium gas sorbents

Measurement of the O2, CO and CO2 sorption characteristics have shown that these films - e.g. those generated electrothermally from Ag/Li solid solutions - excel the best getters of the Ba-film type or the high porosity getters based on Ti, V and Zr alloys. It has been found that tight lithium films passivate as a sorption depth of approximately 100 Å is reached. Methods for further improvement of the sorption behavior of lithium coatings are discussed.
