摘要： An evaporable getter device is provided for cathode-ray tubes (CRTs). The getter device is formed by a metallic container (101; 201) containing a mixture of powders (104; 205) of the compound BaAl4 and nickel (Ni), and by two different metallic nets (106, 107; 207, 208), 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.
