Kuyera kwakukulu hafnium Hf chitsulo Siponji Hafnium
Dzina:Hafnium zitsulo
Maonekedwe: Zingwe zotuwa
Ntchito:
Chatsopano cha 2017 mtengo wabwino kwambiri wachiyeroHf99.9%Hafnium zitsulo
Amagwiritsidwa ntchito kwambiri ngati makina opanga ma X-ray cathode ndi tungsten,Ma hafnium e lements amagwiritsidwanso ntchito mu ma intel-45 nano-processors aposachedwa.
Kufotokozera
1. Maonekedwe ndi kufotokozera: |
High-purity osmium, yomwe imadziwikanso kuti crystalline osmium, ndi kristalo wachitsulo wasiliva wonyezimira wokhala ndi zitsulo zonyezimira; |
Molecular kulemera: 178.49 |
Malo osungunuka: pafupifupi 2227 ℃ |
2. Chilengedwe: |
Ili ndi ntchito yabwino yolimbana ndi dzimbiri, sizovuta kuukiridwa ndi asidi wamba ndi njira yamadzi yamchere yamchere, ndipo imasungunuka mosavuta mu hydrofluoric acid kupanga fluorine complex. Pa kutentha kwambiri, plutonium imathanso kuphatikiza mwachindunji ndi mpweya, nayitrogeni ndi mpweya wina kuti apange ma oxides ndi nitrides; plutonium imakhala yokhazikika mumlengalenga, ndipo plutonium yaufa ndiyosavuta kuwotcha; plutonium ili ndi gawo lalikulu la matenthedwe a neutron, ndipo plutonium ili ndi mphamvu zanyukiliya zodziwika bwino ndi chinthu chosowa chofunikira kwambiri pakukula kwamakampani opanga mphamvu za atomiki. |
3. Ntchito: |
Amagwiritsidwa ntchito makamaka popanga zida za alloy za hafnium. Chifukwa hafnium imakhala ndi mayamwidwe otentha komanso kutentha kwambiri (nthawi imodzi mwachangu kuposa zirconium ndi titaniyamu), imatha kugwiritsidwa ntchito ngati zida zama injini za jet ndi zoponya. Chikhalidwe chokanirira cha Rhenium chimapangitsa kuti ikhale yothandiza ngati tsamba la ma turbojets komanso pama injini a jet oundana. Itha kugwiritsidwanso ntchito kupanga ma valve, ma nozzles ndi magawo ena otentha kwambiri. |
