Zirconium (Zr) Rau Kev Lag Luam
Cov khoom tseem ceeb ntawm zirconium hlau yog siab zog thiab zoo heev corrosion kuj thaum alloyed nrog lwm yam ntaub ntawv. Cov hlau no yog tsim rau kev lag luam, marine thiab lwm qhov chaw ib puag ncig thiab muaj kev ua haujlwm zoo metallurgical thiab kev qaug zog zoo heev.
Hauj lwm lawm
Glittering zoo li pob zeb diamond, zirconium muaj ntau yam kev siv. Ntxiv nrog rau nws siv nyob rau hauv cov hniav nyiaj hniav kub sector, zirconium yog ib tug semi-precious pob zeb mas siv nyob rau hauv daim ntawv ntawm alloys nyob rau hauv lub nuclear kev lag luam. Nws qhov tshwj xeeb tsis kam mus rau qhov kub thiab txias, nws cov corrosion kuj thiab nws cov pob tshab rau neutrons ua rau nws cov alloy ntawm kev xaiv rau ntau yam txheej txheem tshuaj.
Khoom Description
Zirconium yog ib qho muaj zog heev, malleable, ductile, lustrous silver-grey hlau. Nws cov khoom siv tshuaj thiab lub cev zoo ib yam li cov titanium. Zirconium yog tsis tshua muaj resistant rau tshav kub thiab corrosion. Zirconium yog sib zog dua hlau thiab nws hardness zoo ib yam li tooj liab. Thaum nws tau muab faib ua kom zoo, cov hlau tuaj yeem tshwm sim nyob rau hauv huab cua, tshwj xeeb tshaj yog thaum kub kub. Zirconium hmoov yog dub thiab suav tias yog hluav taws kub txaus ntshai heev. Zirconium tsis yaj hauv cov kua qaub thiab alkalis.

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.
