ABSTRACT:
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.
