Hafnium Hlau

Hafnium hlau yog cov khoom siv los ntawm cov hlau hafnium, nrog cov nyiaj dawb luster, lub melting point ntawm 2227 degree C, thiab qhov ceev ntawm 13.1 grams ib cubic centimeter. Hafnium hlau muaj cov khoom zoo ntawm qhov kub thiab txias, thiab nws cov corrosion kuj zoo dua li titanium, mus txog ntawm tantalum thiab niobium. Hafnium tuaj yeem nqus tau ntau cov pa roj xws li oxygen, hydrogen, thiab nitrogen thaum lub sijhawm cua sov, ua rau nws zoo tagnrho cov pa nqus.

Cov txheej txheem kev npaj ntawm hafnium hlau yog complex, feem ntau suav nrog decomposition ntawm ore, sib cais ntawm zirconium thiab hafnium, theem nrab chlorination ntawm HfO2, purification thiab magnesium txo ntawm HfCl4, thiab nqus distillation ntawm crude sponge hafnium. Qhov kawg daim txhuam cev hafnium yog ua tiav los ntawm forging, dov, teb forging, thiab kos duab los tsim cov xaim hafnium.

Hafnium hlau feem ntau yog siv los ua cov khoom siv lub taub hau electrode rau plasma txiav tshuab. Vim nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, hafnium hlau tuaj yeem tiv taus qhov kub thiab txias ib puag ncig, ua kom muaj kev ruaj ntseg thiab ua haujlwm ntawm cov txheej txheem txiav. Plasma txiav yog ib txoj kev txiav tus nqi qis, thiab cov tub ntxhais ntawm cov electrode yog hafnium hlau embedded rau hauv tooj liab substrate. Qhov zoo ntawm hafnium hlau ncaj qha cuam tshuam rau lub neej kev pab cuam thiab txiav cov nyhuv ntawm electrode. Hafnium hlau ua lub luag haujlwm tseem ceeb hauv kev lag luam atomic zog. Ntshiab hafnium yog cov khoom tseem ceeb hauv kev lag luam atomic zog vim nws cov yas, yooj yim ntawm kev ua, kub tsis kam, thiab corrosion kuj. Hauv particular, hafnium muaj qhov loj thermal neutron ntes hla ntu thiab yog ib qho zoo tagnrho neutron absorber. Yog li ntawd, nws yog feem ntau siv los ua cov kav hlau txais xov thiab cov cuab yeej tiv thaiv rau cov atomic nuclear reactors kom qeeb tus nqi ntawm cov kev cuam tshuam ntawm cov saw hlau nuclear thiab txo cov "nplaim" ntawm cov tshuaj tiv thaiv atomic.

Hauv kev lag luam hluav taws xob, hafnium hlau tuaj yeem siv los tsim cov cathodes rau X-ray raj. Daim ntawv thov no siv qhov ruaj khov ntawm hafnium hlau nyob rau hauv qhov kub thiab txias thiab lub tshuab nqus tsev. Hafnium kuj tseem siv tau los ua cov khoom siv ntxiv hauv kev tsim cov khoom siv tawv tawv thiab cov hlau tsis muaj cua sov. Piv txwv li, hafnium carbide (HfC), ib tug compound ntawm hafnium thiab carbon, yuav siv tau raws li ib tug additive nyob rau hauv nyuaj alloys vim nws siab hardness thiab melting point. Lub melting point ntawm 4TaC · HfC yog siab li 4215 degree, ua rau nws yog ib tug ntawm cov tebchaw nrog lub siab tshaj plaws melting point ntawm cov ntaub ntawv paub. Hafnium kuj tseem siv tau los ua tus neeg sawv cev nqus dej hauv ntau lub tshuab nyiaj txiag kom tshem tawm cov pa tsis zoo xws li oxygen thiab nitrogen tam sim no hauv lub cev. Txawm hais tias ntshiab hafnium hlau electrodes muaj corrosion kuj zoo thiab plasticity, lawv cov electrochemical kev ua tau zoo yog qis dua rau cov hlau electrodes. Yog li nyob rau hauv cov xwm txheej uas cov kev xav tau vuam yog qhov siab, hafnium alloy hlau yuav yog qhov kev xaiv zoo dua.

Hafnium yog cov hlau tsis tshua muaj cov ntsiab lus tsawg hauv lub ntiaj teb lub pob zeb, thiab cov txheej txheem kev rho tawm thiab kev ua haujlwm yog qhov nyuaj, ua rau muaj nqi ntau dua rau cov hlau hafnium. Qhov no rau qee qhov txwv nws daim ntawv thov hauv qee thaj chaw. Hafnium hlau yuav tsum muaj cov txheej txheem tshwj xeeb thiab cov cuab yeej siv thaum lub sijhawm ua, xws li forging, extrusion, thiab cov duab kos, uas muaj cov kev xav tau siab rau kev siv tshuab thiab khoom siv. Qhov no tseem ua rau qhov nyuaj thiab tus nqi ntawm kev ua haujlwm.

Nyob rau hauv luv luv, hafnium hlau yuav tsum tau ua tib zoo xav txog nws qhov zoo thiab qhov tsis zoo ntawm daim ntawv thov, thiab cov ntaub ntawv tsim nyog thiab cov txheej txheem yuav tsum raug xaiv raws li qhov tshwj xeeb daim ntawv thov scenarios thiab cov cai.
