Zirconium yog cov khoom siv tshuaj nrog lub cim Zr thiab atomic tooj 40. Lub npe zirconium yog muab los ntawm lub npe ntawm cov ntxhia zircon, qhov tseem ceeb tshaj plaws ntawm zirconium. Nws yog ib qho lustrous, grey-dawb, muaj zog hloov hlau uas zoo ib yam li hafnium thiab, rau qhov tsawg dua, titanium.
Zirconium yuav pom qhov twg?
Zirconium tshwm sim hauv kwv yees li 30 hom pob zeb, qhov loj yog zircon thiab baddeleyite. Ntau tshaj 1.5 lab tonnes ntawm zircon raug mined txhua xyoo, feem ntau hauv Australia thiab South Africa. Feem ntau baddeleyite yog mined hauv Brazil.
Zirconium nyob qhov twg hauv Asmeskas?
Hauv Tebchaws Meskas, zirconium yog mined hauv Florida thiab Georgia.
Puas muaj zirconium hauv cov zaub mov?
Zirconium muaj nyob rau hauv ntau yam khoom noj, qee yam yog European plum, parsley, carrot, thiab endive.
Zirconium puas tsim kev puas tsuaj rau tib neeg?
Toxicity Feem ntau cov zirconium tebchaw muaj tsis muaj kab mob toxicity vim lawv tsis zoo solubility. Txawm li cas los xij, qee qhov sib xyaw ua ke, xws li zirconium tetrachloride, ua rau khaus thiab tuaj yeem ua rau raug mob. Tsis tas li ntawd, daim tawv nqaij thiab lub ntsws granulomas tau raug tshaj tawm tom qab rov raug zirconium.
Pom zoo:
Puas tau pom zoo lossis tau pom zoo?
"Tau pom zoo" yog tam sim no zoo meej, tsis yog tam sim no nce qib (uas yuav yog "kev pom zoo" - qhia tias "kev pom zoo" tam sim no tab tom ua). Puas tau pom zoo txhais? 1: kom muaj lossis nthuav tawm qhov kev pom zoo tsis tuaj yeem pom zoo li kev coj ua.
Puas pom ze ze ua rau qhov muag tsis pom?
Kev mob myopia siab tuaj yeem ua rau koj tus menyuam muaj kev pheej hmoo ntawm kev pom kev mob hnyav dua tom qabhauv lub neej, xws li cataracts, detached retinas thiab glaucoma. Sab laug tsis kho, qhov mob myopia siab tuaj yeem ua rau dig muag, yog li kev kuaj qhov muag tsis tu ncua yog qhov tseem ceeb.
Zirconium feem ntau pom nyob qhov twg hauv ntiaj teb?
Nyob ntiaj teb, qhov chaw rau zirconium feem ntau yog cov ntxhia zircon thiab baddeleyite (zirconium dioxide zirconium dioxide Zirconia tuaj yeem siv ua photocatalyst txij li nws qhov sib txawv siab (~ 5 eV)tso cai tiam ntawm cov muaj zog electrons thiab qhov.
Koj puas tuaj yeem hloov kho zirconium rings?
Dub zirconium thiab tungsten carbide rings nyob ze tsis tuaj yeem hloov pauv. Thaum titanium thiab stainless hlau rings tuaj yeem hloov kho, nws tseem nyuaj heev, thiab yog tias ua tau, feem ntau tsuas yog hloov pauv hauv qhov txwv. Ib yam uas yuav tsum nco ntsoov yog tias koj yuav lub nplhaib ua los ntawm cov ntaub ntawv no!
Puas tau pom Mauxe lub ntxa puas tau pom?
Mauxes tau hais tias tau tuag hauv Mount Nebo, Jordan. Raws li Vajluskub hais, qhov chaw tseeb ntawm Mauxes lub ntxa tseem tsis paub, txhawm rau tiv thaiv kev pe mlom. Lub ntxa ntawm Aaron, nyob rau hauv Mount Harun, ze Petra, Jordan. Adas thiab Eva faus nyob qhov twg?
