Getter materials comprising non-evaporable getter alloys in their powder form having high gas sorption efficiency, particularly for hydrogen, carbon oxide and nitrogen, which after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a temperature between 400 and 600 °C. Said alloy powders comprise as compositional elements titanium and silicon and at least one additional metallic element selected among vanadium, iron and aluminum and have an atomic percentage composition of said elements which can vary within the following ranges: 1. titanium from 60 to 85 at.%; 2. silicon from 1 to 20 at.%; and 3. the sum of vanadium, iron and aluminum from 10 to 30 at.%. |
