tungsten eletrode high melting point (3683 ℃ ± 20 ℃), the electron emission capability, high modulus, low vapor pressure, so it has long been used as a thermal electron emission material [. Pure tungsten electrode emission efficiency is low and at high temperatures the formation of equiaxed recrystallized grains leaving the filament sag, break. To overcome these shortcomings, to adapt to modern industrial new technologies, new technology development, national materials workers are committed to research and development of new electrode materials. Some doped tungsten-based low electron work function of rare earth oxides, both to improve the recrystallization temperature, but also activate the electron emission. Rare earth metal oxide has excellent thermal electron emission capability, rare earth tungsten electrode material has been an alternative to conventional radioactive thoriated tungsten electrode material development direction. This article describes several rare earth tungsten electrode material preparation and research, as well as the electrode material on the application of the situation and prospects of the tungsten electrode potential applications, designed for China's rare earth tungsten electrode materials research and application of reference.
