Hafnium Rod

Shaanxi Zhongheng Weichuang Hlau Khoom Co., Ltd. muab cov khoom zoo siab hafnium hlau rods nrog ib tug purity txog li 99.95%, thiab tuaj yeem kho qhov tshwj xeeb raws li qhov xav tau. Hafnium pas nrig yog cov nyiaj grey hlau nrog cov xim hlau nplaum thiab qhov ntom ntom ntawm li 13.31 grams ib cubic centimeter. Qhov no ua rau hafnium pas nrig muaj qhov loj ntawm tib lub ntim thiab haum rau cov ntawv thov uas xav tau cov ntaub ntawv siab. Lub melting point ntawm hafnium yog tsis tshua muaj siab, uas tso cai rau hafnium rods kom ruaj khov kev ua tau zoo nyob rau hauv high kub ib puag ncig thiab tsis yooj yim melted los yog deformed.

 

 

Hafnium rods muaj corrosion kuj zoo thiab tsis yooj yim corroded los ntawm cov kua qaub thiab alkaline aqueous daws. Cov yam ntxwv no ua rau hafnium rods muaj kev thov dav dav hauv kev lag luam tshuaj thiab lwm qhov chaw corrosive. Hafnium tuaj yeem txuas ncaj qha nrog cov pa roj xws li oxygen thiab nitrogen ntawm qhov kub thiab txias los tsim oxides thiab nitrides. Txawm li cas los xij, nyob rau hauv chav tsev kub, hafnium rods kuj ruaj khov thiab tsis yooj yim reactive nrog lwm yam tshuaj. Hafnium rods yog insoluble nyob rau hauv dilute hydrochloric acid, dilute sulfuric acid, thiab muaj zog alkaline daws, tab sis yog yooj yim soluble nyob rau hauv hydrofluoric acid thiab aqua regia. Cov yam ntxwv solubility no ua rau hafnium rods muaj qhov tshwj xeeb daim ntawv thov tus nqi hauv cov tshuaj tiv thaiv tshwj xeeb.

Hafnium rods muaj plasticity nyob rau hauv lub xeev ntshiab, tab sis lawv ua tawv thiab nkig thaum impurities muaj. Cov yam ntxwv no yuav tsum tau saib xyuas nws cov purity thiab impurity cov ntsiab lus thaum siv hafnium rods kom tsis txhob cuam tshuam rau cov khoom siv kho tshuab. Hafnium muaj qhov siab ntawm neutron absorption cross section thiab yog ib qho zoo tagnrho neutron absorber. Yog li ntawd, nws feem ntau yog siv los ua tus pas ntsuas hluav taws xob hauv nuclear reactors kom qeeb tus nqi ntawm kev sib txuas lus nuclear thiab suppress "teeb" ntawm atomic tshua. Hauv nuclear reactors, hafnium rods kuj tseem siv tau los ua lwm yam tseem ceeb, xws li cov cuab yeej tiv thaiv, kom ntseeg tau tias kev ua haujlwm nyab xeeb ntawm lub tshuab hluav taws xob nuclear.

Hafnium rods tuaj yeem siv los ua alloy additives rau aviation thiab aerospace cov ntaub ntawv los txhim kho lawv cov kub tsis kam, corrosion kuj, thiab lwm yam khoom, ua tau raws li qhov xav tau ntawm huab cua puag ncig. Vim nws txoj kev nqus cua kub sai thiab tso tawm cov khoom, nrog rau cov khoom zoo heev, hafnium tuaj yeem siv los ua cov khoom siv dav hlau thiab cov cuaj luaj, xws li cov hniav rau cov dav hlau turbojet.

Ntxiv cov khoom hafnium rau cov alloys xws li tungsten, molybdenum, thiab tantalum tuaj yeem tsim cov alloys nyuaj thiab cov hlau tsis muaj cua sov, uas muaj kev siv dav hauv cov cuab yeej txiav, cov khoom kub kub, thiab lwm yam. 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. Hafnium rods kuj tseem siv rau lub tshuab nqus tsev sputtering txheej, raws li cov ntaub ntawv rau lub vaj huam sib luag tiaj tus, cov txheej txheem zoo nkauj, cov cuab yeej thiab pwm txheej, iav txheej, cov khoom siv hluav taws xob, cov txheej txheem sib nqus, cov txheej txheem semiconductor, thiab cov txheej txheem hnub ci. Hauv kev lag luam electronics, hafnium rods yog siv los tsim cathodes rau X-ray raj.

Hafnium rods tau txais txiaj ntsig zoo rau lawv lub cev, tshuaj, thiab cov khoom siv kho tshuab, nrog rau lawv cov kev siv ntau yam. Tab sis tib lub sijhawm, tus nqi kuj tseem siab dua piv rau tantalum thiab niobium, thiab tuaj yeem xaiv tau raws li cov kev thov tshwj xeeb thiab cov peev nyiaj.
