Zirconium ntawv
Zirconium (Zr) yog cov hlau silvery nrog qhov ceev ntawm 6.52 g / cm3. Zirconium muaj ib qho me me ntawm neutron absorption cross-section thiab ib qho tseem ceeb melting point (1855 degree lossis 3371 degree F), ua rau nws zoo tagnrho rau cov pas nrig nuclear.
Hauj lwm lawm
Hauv xyoo 1990, kwv yees li 90% ntawm cov zirconium tsim txhua xyoo tau noj los ntawm kev lag luam nuclear. Txawm li cas los xij, raws li ntau thiab ntau tus neeg tau paub txog zirconium thiab nws cov tebchaw, ntau qhov chaw ntawm daim ntawv thov tau pom. Hlau zirconium thiab zirconium alloys muaj txiaj ntsig zoo hauv thaj chaw tshwj xeeb tshuaj, feem ntau acetic thiab hydrochloric acids. Lub corrosion kuj ntawm zirconium los ntawm yuav luag instantaneous tsim ntawm nruj adherent oxides.

Vim li no, zirconium tau siv los ua cov khoom siv tshwj xeeb electrode, foils, flange bolts, raj thiab rods. Zirconium phaj yog dav siv hauv cov khoom siv kho mob. Zirconium daim hlau kuj tseem siv tau los ua kev txhawb nqa thiab cov khoom siv rau cov ntawv thov kub vim lawv lub zog zoo zog ntawm qhov kub thiab txias.
Khoom ntim
txog peb
Tsim los ntawm 2008, lub tuam txhab tau loj hlob ntau xyoo dhau los ua cov chaw tsim khoom thiab cov khoom siv hlau ua haujlwm rau ntau yam kev lag luam. Lub tuam txhab tsis tu ncua nqis peev hauv kev tshawb fawb thiab kev tsim kho kom zoo dua qub thiab ruaj khov ntawm nws cov khoom. Lub tuam txhab tso siab rau cov neeg siv khoom txaus siab thiab paub txog kev muab cov khoom zoo thiab kev pabcuam zoo rau cov neeg siv khoom. Niaj hnub no, lub tuam txhab muaj lub ntiaj teb no nyob thiab pab cov neeg muas zaub nyob rau hauv lub teb chaws thoob plaws lub ntiaj teb no.
