Abstract
Zr-Fe alloys (15%-30% by wt Fe, balance Zr) start to sorb hydrogen at temperatures between 200.degree. and 250.degree. C. They are particularly useful for the sorption of hydrogen within the outer jacket of high intensity discharge lamps.
Claims2
A method for sorbing hydrogen in a vacuum tube comprising the steps of
- I. introducing into the vacuum tube a powdered getter metal which is an alloy of from 15 to 30 weight percent iron, balance zirconium;
- and then
- II. heating the getter metal to a temperature at which hydrogen sorption commences.
A method of sorbing hydrogen in a vacuum tube comprising the steps of:
- I. introducing into the vacuum tube a powdered getter metal, having a particle size of from 1 to 125 microns, wherein the getter metal consists essentially of Zr.sub.2 Fe;
- and then
- II. heating the powdered getter metal to a temperature of 200.degree. to 250.degree. C.;
- and then
- III. sorbing hydrogen by means of the powdered getter metal in the presence of nitrogen.
