Getter devices with improved sorption rate based on powders of ternary alloys particularly suitable for hydrogen and carbon monoxide sorption are described, said alloys having a composition comprising zirconium, vanadium and aluminum as main constituent elements.

Non-evaporable getter alloys particularly suitable for hydrogen and carbon monoxide sorption

Getter devices with improved sorption rate, based on powders of quaternary alloys particularly suitable for hydrogen and carbon monoxide sorption, are described. Quaternary alloys having a composition comprising zirconium, vanadium, titanium and aluminum as main constituent elements are also described.

A composition of precursors for the release of vapors of alkali or alkali-earth metals is described. The composition has at least a compound of alkali or alkali-earth metal, at least a reducing agent and optionally an absorbing material, all in the form of powders, dispersed in a viscous matrix of hybrid organic-inorganic type. Dispensers for the release of these metals obtained through the composition and micro-electronic devices are also described.

Getter materials are described. The getter materials have 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&#xb0; C. and 600&#xb0; C. The alloy powders have 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 the elements which can vary within the following ranges: 1. Titanium from 60 to 85 atomic percentage; 2. Silicon from 1 to 20 atomic percentage; and 3. The sum of vanadium, iron and aluminum from 10 to 30 atomic percentage.

Getter alloys particularly suitable for hydrogen sorption are described. The getter alloys include a first element consisting of yttrium or a yttrium equivalent mixture, the first element forming at least 30% by atoms of the alloy. A method for removing hydrogen from devices which are sensitive to the presence thereof and hydrogen-sensitive devices which contain the described getter alloys are also described.
