USE OF NON-EVAPORABLE GETTER ALLOYS FOR THE SORPTION OF HYDROGEN IN VACUUM AND IN INERT GASES

摘要

It is described the use of non-evaporable getter alloys for hydrogen absorption inside evacuated chambers or from inert gases, both in applications where these latter represent the filling gas of device chambers, and for use in flows of the same gases for their purification. The alloys have the composition of the following polygon when plotted in a ternary diagram: a) Zr 54% - Y 1% - M 45% b) Zr 50% - Y 5% - M 45% O Zr 50% - Y 20% - M 30% d) Zr 75% - Y 20% - M 5% e) Zr 80% - Y 15% - M 5% f ) Zr 80% - Y 1% - M19%.
