Cov khoom siv hluav taws xob
Vim tias hafnium emits cov hluav taws xob tau yooj yim, nws tuaj yeem siv los ua cathode hauv txoj kab xoo hluav taws xob. Ib qho ntxiv, alloys ntawm hafnium thiab tungsten lossis molybdenum yog siv los ua cov khoom siv hluav taws xob rau cov hluav taws xob muaj hluav taws xob tsis zoo. Xyoo 2012, pab pawg kws tshawb fawb coj los ntawm Andrew Flovett ntawm University of Cambridge, UK, tau tsim ib hom tshiab ntawm hafnium oxide nrog qhov siab tshaj qhov qub tsis tu ncua, uas yuav siv tau los ua cov cim txuas ntxiv ntawm cov khoom siv hluav taws xob me, cov cuab yeej tsim khoom lag luam photovoltaic thiab ntau cov hlwb photovoltaic.
Kev lag luam atomic zog
Hafnium thov rau reactor hlau hafnium muaj kev ua zoo vuam kev ua haujlwm, kev ua haujlwm zoo, siab kub tsis kam thiab ua hauj corrosion, yog li nws tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam atomic energy kev lag luam. Txij li thaum hafnium muaj qhov loj loj thermal neutron ntes hla ntu, nws yog qhov zoo tshaj plaws neutron absorber thiab tuaj yeem siv los ua kev tswj cov pas nrig thiab tiv thaiv cov khoom hauv atomic reactor.
Kev lag luam chemical
Hafnium tuaj yeem siv los ua cov neeg tau txais hauv ntau lub zog. Tus hafnium getter tshem cov roj tsis huv xws li cov pa thiab nitrogen uas muaj nyob hauv qhov system. Tsis tas li ntawd, hafnium muaj qhov muaj zog tiv thaiv tsis txaus, feem ntau siv los ua cov roj ntxiv rau cov roj hydraulic, txhawm rau tiv thaiv cov hluav taws xob hydraulic roj hauv kev ua haujlwm siab.
Cov khoom siv alloy
Hafnium muaj cov yam ntxwv ntawm ductility, oxidation tsis kam thiab siab kub ua hauj. Nws tseem yog cov khoom siv alloy zoo thiab yog siv ntau hom alloys. Piv txwv, hafniobium alloy muaj 10% hafnium tuaj yeem siv cov nozzle ntawm lub lunar foob pob zeb, thaum lub tantalum tungsten alloy uas muaj 2% hafnium tuaj yeem siv los ua cov khoom tiv thaiv ntawm cov khoom huab cua vim nws lub zog siab.
