Evaporable Getters

SAES Getters' development of monochrome, color picture and display tube getters has been continuous for the last 70 years.

Getter development began with the mass production of the stable barium-aluminum alloy (BaAl4), followed by the introduction of the ring-shaped exothermic and nitrogen-doped getters. The Frittable getters enabled the production of the first rectangular color cathode ray tube (CCRT) in the Sixties.

With the advent of soft-flash technology, SAES Getters Group’s R&D laboratories developed the high-wall, closed centre getter with wire supports for use in normal neck tubes, 20 mm in diameter, and in mini-neck tubes, 22.5 mm diameter.
