Abstract
An evaporable getter device is provided for cathode-ray tubes (CRTs). The getter device is formed by a metallic container () containing a mixture of powders () of the compound BaAland nickel (Ni), and by two different metallic nets (), superimposed and positioned in the container over the powders. The device allows one to obtain a barium distribution in the CRT that is more uniform and wider than that obtainable with a conventional getter device.
