Uses. Nuclear power engineering.
Production of special ceramics, glass, control rods of nuclear boilers.
Metallurgy
Alloying of heat resisting steels.
Optics
Manufacture of multilayered and astronomical x-ray mirrors, fibre optics filaments, night vision devices.
Radio Electronics
Low yield of electrons allows to produce from hafnium cathodes of powerful electron guns, radio-lamps and thermionic effective electrogenerators (3.53 eV).
Electrical Engineering
Manufacture of electrodes for welding low-carbon steel in an argon, CO2 atmosphere, where these electrodes were four times more efficient than tungsten electrodes.
