Abstract

Yttrium-based getter alloys are described which are provided with high capacity of sorbing hydrogen and a low equilibrium pressure of said gas at temperatures of about 700 °C, to be used in hydrogen-sensitive high temperature applications. Some getter devices making use of these alloys are also described.
