Amfanin Samfura
Amfani da Hafnium yana iyakance saboda ƙarancin yawa. Babban amfani da hafnium shine a cikin masana'antar nukiliya, inda ake amfani da shi a cikin sandunan mai don daidaita fission idan aka yi la'akari da babban sashin shayarwar Neutron. Hakazalika da zirconium, an haɗa hafnium tare da niobium da carbide don samar da kayan hana zafin zafin jiki don tanda da abubuwan jet har ma da masu yankan plasma. Bugu da ƙari, ana ƙara amfani da hafnium oxide don ƙarawa ko maye gurbin kwakwalwan kwamfuta na microprocessor na silicone oxide a cikin wasu aikace-aikace har ma a cikin cathodes da capacitors (Field et al., 2011). Hafnium yana da alaƙa mai girma don ɗaukar jinkirin neutrons.
