ホウ素過剰LaB_6・CeB_6単結晶の育成と熱電子放射特性  [in Japanese] Crystal Growth and Thermionic Emission Properties of Boron-Rich LaB_6 and CeB_6  [in Japanese]

Abstract

LaB_<6.0-6.14> and CeB_<6.0-6.12> crystals were prepared by the floating zone method. Their thermionic emission properties were examined in the temperature range of 1100-1500℃. Increasing the boron contents hardly influenced the emission characteristics, but decreased the evaporation rate which determines the life time of the cathodes. Therefore, the boron-rich LaB_6 and CeB_6 crystal cathodes are expected to have longer life time than the stoichiometric commercial cathodes.
