dc.description.abstractIn this paper it is reported the fabrication process of electron emitting barium-calcium aluminates used on impregnated cathodes which constitute high power vaccum microwave devices such as klystrons and TWTs (traveling wave tubes). The compound thermal behavior and the analysis of the formed phases during processing are evaluated, respectively, by means of thermal analysis and XRay diffraction. Results about the influence of firing temperature and atmosphere are also presented. Index Terms — Aluminates, cathodes, electron thermionic emission, thermal analysis, X-Ray diffraction.
