1. Cov tsos thiab piav qhia:

High-purity hafnium, tseem hu ua crystalline hafnium, yog cov nyiaj-grey hlau siv lead ua nrog cov xim hlau nplaum; Cov tshuaj formula: Hf; Molecular Luj: 178.49 Ceev: 13.31 g / cm3; Melting point: txog 2227 ℃ Boiling point: txog 4602 ℃.

2. Khoom:

Nws muaj kev tiv thaiv corrosion zoo, tsis yooj yim corroded los ntawm cov kua qaub thiab alkali aqueous daws, thiab yooj yim soluble hauv hydrofluoric acid los tsim fluorine complexes. Thaum qhov kub thiab txias, hafnium kuj tuaj yeem ua ke ncaj qha nrog oxygen, nitrogen thiab lwm yam gases los tsim oxides thiab nitrides; hafnium tseem ruaj khov nyob rau hauv cov huab cua, thiab hmoov hafnium yog heev yooj yim mus hlawv; hafnium muaj ib tug loj thermal neutron capture cross-section, thiab hafnium muaj ib tug tseem ceeb Nuclear zog yog ib yam khoom uas tsis tshua muaj indispensable rau txoj kev loj hlob ntawm lub atomic zog kev lag luam.

3. Lub Hom Phiaj:

Feem ntau yog siv rau hauv kev tsim cov khoom siv hafnium-raws li alloy, hniav nyiaj hniav kub ntxiv, alloy smelting ntxiv, CVD evaporation txheej thiab lwm yam lag luam. Nws kuj yog siv nyob rau hauv atomic zog teb los yog nyob rau hauv cov tub rog teb.
