Zirconium chloride, tseem hu uaZirconium (IV) Chloride or Zenc4, yog qhov sib xyaw ua ke nyob rau ntau yam kev lag luam thiab kev tshawb fawb. Nws yog tus dawb crystalline khoom nrog molecular cov mis ntawmZenc4thiab txoj kev molecular hnyav ntawm 233.09 g / mol.Zirconium chlorideyog cov kev hloov kho siab heev thiab muaj ntau cov kev siv, los ntawm catalysts thiab tshuaj synthesis rau kev tsim cov ceramics thiab tsom iav. Hauv tsab xov xwm no, peb yuav saib yuav ua li caszirconium chlorideyog ua.
Cov synthesis ntawmzirconium chloridekoom nrog cov tshuaj tiv thaiv nruab nrab ntawmzirconium oxidelossis zirconium hlau thiab hydrogen chloride.Zirconia (Rau 40) yog feem ntau siv raws li qhov pib cov khoom vim nws muaj thiab ruaj khov. Cov tshuaj tiv thaiv tuaj yeem nqa tawm nyob rau hauv lub xub ntiag ntawm tus neeg sawv cev txo xws li carbon lossis hydrogen los txhawb kev hloov dua siab tshiab ntawmZirconium oxide itus ntseszirconium hlau.
Ua ntej,zirconiayog tov nrog tus neeg sawv cev txo qis thiab muab tso rau hauv lub nkoj uas tsis sib haum. Hydrogen chloride roj yog tau qhia rau hauv lub nkoj uas ua rau muaj cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv yuav ua tau exothermic, lub ntsiab lus nws tso tawm thaum tshav kub kub, thiab yuav tsum tau nqa tawm hauv cov xwm txheej tswj tau kom tiv thaiv qee cov kev phom sij. Cov tshuaj tiv thaiv nruab nrab ntawmzirconium oxidethiab hydrogen chloride yog raws li hauv qab no:
ZO2 + 4HCL → ZRCL4 + 2H2O
Cov tshuaj tiv thaiv feem ntau nqa tawm ntawm qhov kub, feem ntau ntawm 400 thiab 600 degrees Celsius, kom paub tseeb tias hloov dua siab tshiab ntawmzirconium oxidemus hauvzirconium chlorideCov. Cov tshuaj tiv thaiv ua kom txog thaum txhua tuszirconium oxideyog 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 ib daim ntawv hydrated, lub ntsiab lus nws muaj cov lwg dej hauv nws cov qauv siv lead. Kom tauanhydous zirconium chloride, hydratedzirconium chloridefeem ntau yog rhuab lossis lub tshuab nqus tsev qhuav kom tshem tawm cov lwg roj.
Purity ntawmzirconium chlorideyog qhov tseem ceeb rau cov ntawv thov tshwj xeeb. Yog li no, ntxiv cov kev ua kom muaj kev lim dej caw tuaj yeem tshem tawm cov impurities lossis ya raws. Cov tswv yim muaj kev siv zog muaj xws li sublimation, fractional crystallization, thiab distillation. Cov hau kev no tuaj yeem rho tawmsiab-purity zirconium chloride, uas yog qhov tseem ceeb rau ntau yam kev lag luam suav nrog cov khoom siv hluav taws xob thiab cov ntawv thov nuclear.
Kom suav txog,zirconium chlorideyog synthesized los ntawm cov tshuaj tiv thaiv ntawmzirconium oxidethiab hydrogen chloride. Cov tshuaj tiv thaiv no yuav tsum tau tswj hwm thiab feem ntau nqa tawm ntawm qhov kub. Lub txiaj ntsigzirconium chlorideFeem ntau yog tau nyob rau hauv ib daim ntawv hydrated, nrog cov kauj ruam ntxiv yuav tsum tau txais anhydrous zirconium chloride. Cov tswv yim siv huv tau tuaj yeem ua haujlwm kom tau txais ntshiabzirconium chloriderau cov ntawv thov tshwj xeeb. Kev tsim khoom ntawmzirconium chlorideyog ib qho txheej txheem tseem ceeb, ua rau nws siv dav hauv ntau yam kev lag luam thiab kev tshawb fawb.
