Abstract

An evaporable getter device that can be frit sealed is described, being capable of releasing barium quantities of at least 300 mg for the use in picture tubes of traditional type or flat displays. The device comprises a container in which there is a mixture of powdered BaAl 4 alloy and nickel, in the form of a packet at the upper surface of which there is a variable number of radial recesses; a discontinuous metallic member is provided within the packet.
