Recent research in the field of gas sorption by Li-IIA alloys has improved our understanding of those processes in the gas-alloy system that influence taking practical decisions. Three features in the behavior of reactive macrobodies with a monolithic structure appeared to be significant and should lead to the replacement of a number of conventional sorption practices with new ones. These include the temporary resistance of the mentioned macrobodies to air (sorption pause), the ultra-fast decay of intermetallic phases according to the laws of corrosion (self-grinding), and the renewal of the reactive melt surface by sedimentation of reaction products with gases into the melt volume (self-cleaning). Applications of the mentioned phenomena for clean technologies are also discussed.
