On icreasing the lifetime of tungsten-based cathode materials
Russian Metallurgy (Metally). 2003. No. 4. P. 376-381.
The stability of the electrophysical properties of tungsten-based compositions is studied in a temperature
range of 1300–1700 K. After high-temperature activation, tungsten–oxide compositions can have an
electrical resistivity that is stable in time, which provides a basis for the fabrication of durable directly heated
hot cathodes and heaters based on them.
