The scope of the present invention is the provision of a non-evaporable gettering ternary alloy particularly for the sorption of water and water vapor in nuclear reactor fuel elements. The ternary gettering alloy has a composition which when plotted on a ternary composition diagram in weight percent Zr, weight percent Ti and weight percent Fe lies within a polygon having as its corners the points defined by

Non-evaporable ternary gettering alloy, particularly for the sorption of

A non-evaporable getter alloy is provided which can be used in a process for the sorption of gas from a closed vessel comprising the step of:

Non-evaporable ternary gettering alloy and method of use for the

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.

Getter device and process for using such

This invention relates to a supported getter device comprising a metallic support structure consisting of a three-dimensional network defining a multiplicity of inter-connecting free cells and a particulate getter material substantially filling at least some of said free cells. This invention also relates to a getter device comprising at least one attachment zone of a compressed three-dimensional metal network attached to at least one supported getter material zone comprising a three-dimensional metal network. Methods of making the getter devices are described.

Supported getter

Zr.sub.2 Ni sorbs both oxygen and hydrogen from water making its use advantageous as a getter metal in a nuclear reactor fuel element.
