Zirconium(Zr) thiabhafnium(Hf) yog ob qho tseem ceeb tsis tshua muaj hlau.Hauv qhov xwm txheej, zirconium feem ntau muaj nyob hauv zircon (ZrO2) thiab zircon (ZrSiO4).Tsis muaj cov ntxhia ntawm hafnium nyob rau hauv qhov xwm txheej, thiab hafnium feem ntau coexists nrog zirconium thiab muaj nyob rau hauv zirconium ores.Hafnium thiab zirconium nyob rau hauv plaub pawg ntawm lub sij hawm ntawm lub ntsiab lus, nrog rau cov khoom zoo sib xws.Vim qhov zoo sib xws atomic radii, tshuaj sib cais yog qhov nyuaj heev.Raws li cov lus hais mus, 'Yog tias muaj zirconium, muaj hafnium, thiab yog tias muaj hafnium, muaj zirconium', qhia txog 'kev sib hlub' ntawm ob tug 'kwv tij' ntawm zirconium thiab hafnium.
Kev sib cais tshuab ntawm zirconium thiab hafnium tseem tab tom tsim.Los ntawm cov txheej txheem boiling chlorination, hluav taws sib cais, rho tawm kev sib cais ntawm zirconium thiab hafnium mus rau tam sim no ntub thiab hluav taws sib cais, kev sib cais nyhuv ntawm zirconium thiab hafnium tau raug txhim kho, uas ua rau ib tug tas mus li purity ntawm downstream khoom.
Precursors uas muaj zirconium thiab hafnium feem ntau yog siv rau hauv cov ntaub ntawv los yog catalysts hauv kev lag luam petrochemical.Zirconium chloride (ZrCl4,kuj hu uazirconium tetrachloride) tuaj yeem tsim los ntawm smelting zircon nrog carbon txo thiab chlorination.Hafnium chloride(HfCl4, kuj hu uaHafnium tetrachloride hmoov) feem ntau yog tsim los ntawm oxidizing hafnium, carbon, thiab ces chlorinating.Zirconium chloridethiabtshuaj hafnium chlorideyog ib qho tseem ceeb raw cov ntaub ntawv rau synthesizing precursors uas muaj zirconium thiab hafnium, uas yog dav siv nyob rau hauv aerospace, petrochemical, nuclear thiab lwm yam teb.
Siv high-purityzirconium tetrachloridethiab hafnium tetrachloride ua raw cov ntaub ntawv, cov khoom xws li n-propanol zirconium / hafnium, n-butanol zirconium / hafnium, tert butanol zirconium / hafnium, ethanol zirconium / hafnium, dichlorodicenyl zirconium / hafnium, thiab buteneclinshafnium dichloridekuj tuaj yeem ua ke.Cov khoom no tuaj yeem ua haujlwm ua hafnium thiab zirconium rau vapor deposition thiab ceramic precursors, nrog rau cov organic synthesis catalysts.Shang hai Epoch cov ntaub ntawv tuaj yeem muab cov khoom ntim tshwj xeeb xws li qib reagent mus rau qib kev lag luam, ntsib ntau yam kev siv xws li kev sim kev tshawb fawb, kev sim cov nroj tsuag, thiab ntau lawm.Nyem rau ntawm qhov txuas mus tshawb nrhiav cov khoom lag luam ntsig txog kom pom cov ncauj lus kom ntxaws.
