Abstract
Complex investigations are performed to study the process of chemical interaction of an alkaline-earth Ca-Mg alloy with the components of air in order to find the prospects of using active metals as an alternative to getter materials applied for gas purification purposes. The sorption activity of Ca-10%Mg alloy on main and adverse gaseous components is experimentally determined from the mass spectra. All chemical reactions occurring during the sorption of gaseous components that determine the overall kinetics of proceeding processes are described.
