NON-VAPORISING GETTER AND METHOD OF OBTAINING THE SAME

Title:

NON-VAPORISING GETTER AND METHOD OF OBTAINING THE SAME

Document Type and Number:

WIPO Patent Application WO/1996/021958

Kind Code:

A2

Abstract:

The proposed non-vaporising getter contains the following components: vanadium (V) - 20-35 wt.%; calcium (Ca) - 0.1-0.5 wt.%; and titanium (Ti) - the rest. The getter has a porosity of 25-65 % of its total volume. In order to obtain the getter in question, a method is proposed whereby a metal powder containing vanadium (V), calcium (Ca) and titanium (Ti) in the proportions indicated above is fed into a deformation zone at a bulk density of about 0.7-1.5 g/cm3. In the deformation zone, the powder is shaped by rolling, producing a getter blank in the form of a ribbon. The latter is cut into uniform sections which are then fed into a heating zone, where a pressure below 1 pa is established and maintained and the blank sections are heated to a temperature below 0.6 of the fusion temperature of the titanium-vanadium alloy and subsequently allowed to set. A getter is obtained with a porosity of 25-65 % of its total volume.
