Technical specifications
Hafnium — refractory heavy metal, density 13.31 g / cm 3. Melting point = 2233 ° C. The capture cross section of thermal neutrons is about 100 barns, which is 2000 times more than zirconium — 0.2 barn.
Percentage composition of hafnium iodide GFI1 GOST 22517−77
| Fe | C | Si | Mn | Ni | Cr | N | Ti | Al | Zr | Ca | Mg | Hf + Zr |
| ≤0.04 | ≤ 0.01 | ≤0.005 | ≤0.0005 | ≤0.05 | ≤0.003 | ≤0.005 | ≤0.005 | ≤0.006 | ≤ 1 | ≤0.01 | ≤0.004 | more than 99.8 |
The cost of hafnium 99% purity is about 780 dollars per 1 kg. 99% purity This metal has an ultrahigh corrosion resistance (higher than that of zirconium). It has increased resistance to aggressive media (hot water, steam, liquid sodium, alkalis, dilute hydrochloric acid, nitric acid of any concentration, organic liquids). It has a higher (than zirconium) level of thermal and radiation resistance.
Application
Adjusting rods of nuclear reactors. The low work function of electrons makes it possible to produce from this metal cathodes of electron guns and thermoemission efficient power generators. Manufacture of electrodes intended for welding low-carbon steel in argon, in an atmosphere of CO 2 .
