Zirconium chloride, kuj hu uazirconium (IV) chloride or ZrCl4, yog ib qho khoom siv feem ntau siv hauv ntau yam kev lag luam thiab kev tshawb fawb tshawb fawb.Nws yog dawb crystalline khoom nrog ib tug molecular mis ntawmZrCl4thiab molecular hnyav ntawm 233.09 g / mol.Zirconium chlorideyog cov reactive heev thiab muaj ntau yam kev siv, los ntawm catalysts thiab tshuaj synthesis rau zus tau tej cov ceramics thiab iav.Hauv tsab xov xwm no, peb yuav saib yuav ua li caszirconium chlorideyog ua.
Lub synthesis ntawmzirconium chloridekoom nrog cov tshuaj tiv thaiv ntawmzirconium oxidelos yog zirconium hlau thiab hydrogen chloride.Zirconia (ZrO2) feem ntau yog siv los ua cov khoom pib vim nws muaj thiab ruaj khov.Cov tshuaj tiv thaiv tuaj yeem ua tau nyob rau hauv lub xub ntiag ntawm tus neeg sawv cev txo qis xws li carbon lossis hydrogen los txhawb kev hloov pauv ntawmzirconium oxide ibntuzirconium hlau.
Ua ntej,zirconiayog tov nrog ib tug txo tus neeg sawv cev thiab muab tso rau hauv ib tug tshuaj tiv thaiv hlab ntsha.Hydrogen chloride gas yog ces nkag mus rau hauv cov tshuaj tiv thaiv hlab ntsha, ua rau cov tshuaj tiv thaiv tshwm sim.Cov tshuaj tiv thaiv yuav yog exothermic, txhais tau tias nws tso cua sov, thiab yuav tsum tau ua raws li kev tswj xyuas kom tsis txhob muaj kev phom sij.Cov tshuaj tiv thaiv ntawmzirconium oxidethiab hydrogen chloride yog raws li nram no:
ZrO2 + 4HCl → ZrCl4 + 2H2O
Cov tshuaj tiv thaiv feem ntau yog ua los ntawm qhov kub thiab txias, feem ntau ntawm 400 thiab 600 degrees Celsius, kom ntseeg tau tias kev hloov pauv tiav.zirconium oxiderau hauvzirconium chloride.Cov tshuaj tiv thaiv mus txog rau tag nrhozirconium oxideyog kiag li hloov dua siab tshiab rauzirconium (IV) chloridethiab dej.
Thaum cov tshuaj tiv thaiv tiav, qhov sib xyaw ua ke yog txias thiab covzirconium chlorideyog sau.Txawm li cas los xij,zirconium chloridefeem ntau muaj nyob rau hauv daim ntawv hydrated, txhais tau tias nws muaj cov dej molecules hauv nws cov qauv siv lead ua.Kom tau txaisanhydrous zirconium chloride, hydratedzirconium chloridefeem ntau yog cua sov los yog lub tshuab nqus tsev qhuav kom tshem tawm cov dej molecules.
Lub purity ntawmzirconium chlorideyog ib qho tseem ceeb rau cov kev siv tshwj xeeb.Yog li ntawd, cov kauj ruam purification ntxiv yuav tsum tau tshem tawm tej impurities los yog ya raws.Cov txheej txheem purification muaj xws li sublimation, fractional crystallization, thiab distillation.Cov txheej txheem no tuaj yeem tshem tawmhigh-purity zirconium chloride, uas yog ib qho tseem ceeb rau ntau yam kev lag luam xws li electronics thiab nuclear kev siv.
Los xaus,zirconium chlorideyog synthesized los ntawm cov tshuaj tiv thaiv ntawmzirconium oxidethiab hydrogen chloride.Cov tshuaj tiv thaiv no yuav tsum tau tswj cov xwm txheej thiab feem ntau yog nqa tawm ntawm qhov kub thiab txias.Qhov tshwm simzirconium chloridefeem ntau tau txais hauv daim ntawv hydrated, nrog rau cov kauj ruam ntxiv yuav tsum tau txais anhydrous zirconium chloride.Cov txheej txheem purification tuaj yeem ua haujlwm kom tau txais cov ntshiabzirconium chloriderau cov ntawv thov tshwj xeeb.Kev tsim tawm ntawmzirconium chlorideyog cov txheej txheem tseem ceeb, ua rau nws siv dav hauv ntau yam kev lag luam thiab kev tshawb fawb tshawb fawb.
