An evaporable getter device containing a mixture of nickel and BaAl,is made to have a shorter barium evaporation time by using a mixture of nickel powders in which the particles of nickel have different morphologies and different specific areas.

Evaporable getter device with reduced activation time

A frittable evaporable getter device includes a metallic container having a disk-shaped bottom wall and a side wall extending upwardly from the bottom wall. A powder compact having an upper surface in which at least two radial recesses are formed is disposed in the container. The powder compact is formed of a mixture of BaAl.sub.4 powder and nickel powder. A discontinuous metallic member is embedded in the powder compact such that the member does not protrude from the upper surface of the powder compact and the member is spaced apart from the bottom wall of the container. An evaporable getter device having reduced activation time includes a powder compact formed of a mixture of BaAl.sub.4 powder, nickel powder, and between about 0.3% and about 5% by weight based on the total weight of the mixture of a third component selected from aluminum, iron, titanium, and alloys thereof.

Frittable-evaporable getters having discontinuous metallic members,

The invention relates to an integrated getter device essentially consisting of at least one evaporable getter device and at least one non-evaporable getter device, wherein the different getter devices circumscribe areas at least partially superimposed or coincident, lying on essentially parallel or coincident planes and preferably arranged in a coaxial way.
