Hafnium Hlau

Hafnium hlau, ua los ntawm cov hlau hafnium. Hauv qhov xwm txheej, hafnium feem ntau koom nrog zirconium. Tag nrho cov minerals uas muaj zirconium muaj hafnium. Hafnium thiab zirconium yog isomorphic. Hafnium feem ntau pom hauv zircon. Nyob ntawm cov duab ntawm qhov hla ntu, hafnium xov hlau tuaj yeem muab faib ua hafnium round xov hlau, hafnium ca xov hlau, hafnium square xov hlau thiab lwm yam.

Taw qhia ntawm Hafnium

Hafnium yog ib qho xim dawb-dawb hlau nrog lub melting point ntawm 2227 degree, lub boiling point ntawm 4602 degree, thiab ib tug ceev (20 degree) ntawm 13.31 g / cm3. Ntshiab hafnium yog yas, yooj yim rau txheej txheem, tiv taus kub thiab corrosion, thiab yog ib yam khoom tseem ceeb rau kev lag luam atomic zog.

Hafnium hlau yog tsim los ntawm electron beam melting ntawm hafnium siv lead ua tuav rau hauv ingots, thiab ces forging, dov, thiab kos duab. Hauv qhov xwm txheej, tsis muaj ib qho hafnium ntxhia. Hafnium ib txwm coexist nrog zirconium. Cov ntsiab lus hafnium ntawm coexisting zirconium ntxhia feem ntau tsuas yog 1% -2% ntawm zirconium, thiab tsuas yog qee cov zaub mov muaj cov ntsiab lus hafnium txog li 5%. Cov txheej txheem kev npaj ntawm hafnium yog complex thiab tus nqi me me, ua rau nws muaj tseeb tsis tshua muaj hlau.

Kev npaj cov txheej txheem ntawm hafnium hlau

Ua ntej, hafnium oxide yog chlorinated los tsim hafnium tetrachloride, uas tom qab ntawd txo qis rau hafnium daim txhuam cev.

Qhov thib ob, nws yog lub tshuab nqus tsev smelted rau hauv hafnium ingots, uas yog kub forged rau hauv hafnium rods.

Thaum kawg, lub hafnium rods yog kub dov rau hauv dov rods, uas yog ces teb forged rau hauv teb forged rods, thiab ces kos rau hauv hafnium hlau.

Cov kev siv tseem ceeb ntawm hafnium hlau hauv kev lag luam

Siv raws li ib tug additive nyob rau hauv ntau yam alloys: Ntxiv hafnium caij pab txoj kev ua tau zoo ntawm cov alloy.

Rau solder: Feem ntau yog siv rau vuam ntawm cov ntaub ntawv hafnium, tus nqi siv tsawg heev

Siv los ua cov khoom siv evaporation: Feem ntau yog siv rau cov txheej txheem kho qhov muag

Siv los ua plasma emitter hauv plasma txiav: Vim nws txoj kev ua haujlwm zoo los tiv thaiv oxidation, zoo thermal conductivity, hluav taws xob conductivity thiab tsis tshua muaj hluav taws xob ua haujlwm.
