An investigation on the phase composition and the electron emission capacity of the aluminate impregnants for the dispenser cathodes

The phase components in the xBaO·CaO·2Al<inf>2</inf>O<inf>3</inf> (where x varies from 5.0 to 6.0) system were investigated by using of the X-ray diffraction. The results illustrate that 5B·C·2A and 6B·C·2A compounds synthesized by co-precipitation are of single-phase with B5CA and B3CA structure after sintering at 1200 °С, respectively. Based on the… CONTINUE READING
