Ülevaade

Hafnium (Hf) General Information：

Hafnium, tähis Hf, aatomnumber 72, aatommass 178.49. Element on läikiv hõbehall siirdemetall. Sulamistemperatuur on 2227 ℃, keemistemperatuur on 4602 ℃, see on vees lahustumatu ja tihedus on 13.31 g/cm3. Hafnium on plastiline metall ja muutub lisandite olemasolul kõvaks ja rabedaks. See on õhu käes stabiilne ja tumeneb ainult põlemisel pinnal. Hõõgniidi saab süüdata tiku leegiga. Tsirkooniumiga sarnased omadused. See ei reageeri vee, lahjendatud happe ega tugeva leelisega, kuid lahustub kergesti regia- ja vesinikfluoriidhappes.

Hafnium is useful because it readily emits electrons (eg, as filament in incandescent lamps). Used as cathodes in X-ray tubes, alloys of hafnium and tungsten or molybdenum are used as electrodes in high-voltage discharge tubes. Commonly used in X-ray cathodes and tungsten wire manufacturing industries. Pure hafnium has plasticity, easy processing, high temperature resistance and corrosion resistance, and is an important material in the atomic energy industry. Hafnium has a large thermal neutron capture cross-section, making it an ideal neutron absorber and can be used as control rods and protective devices in atomic reactors. Hafnium powder can be used as a rocket propeller. In the electrical industry, cathodes of X-ray tubes can be manufactured. Hafnium alloys can be used as front-end protective layers for rocket nozzles and gliding re-entry vehicles. Hf-Ta alloys can be used to make tool steel and resistance materials. Hafnium is used as an additive element in heat-resistant alloys.
