Nws muaj ntau cov kev thov tseem ceeb, xws li catalysts, cov khoom siv ceramic, thiab cov teb biomedical.CAS: 14475-63-9; 12688-15-2
2. Txheej Txheem
Cov molecular qauv ntawmZirconium hydroxide isZr (huag) 4, uas yog muaj li ntawm ib zirconium ion (ZR4 +) thiab plaub hydroxide ions (Oh -). Hauv cov teeb meem hauv lub xeev, tus qauv ntawmZirconium hydroxideyog tsim los ntawm ionic sib khi ntawm zirconium ions thiab hydroxide ions. Qhov zoo ntawm zirconium ions thiab tus nqi tsis zoo ntawm hydroxide ons nyiam ib leeg, sib sau ua cov qauv siv lead ua ruaj khov.
3. Lub cev lub cev
Zirconium hydroxideyog cov khoom siv dawb uas zoo li hmoov lossis cov khoom hauv cov tsos. Nws qhov ntom yog li 3.28 g / cm ³, melting point yog kwv yees li 270 ° C.Zirconium hydroxidePuas yuav luag Insoluble hauv dej ntawm chav tsev kub, tab sis soluble hauv cov kua qaub. Nws solubility nce nrog kev nce ntawm kub.Zirconium hydroxideMuaj cov zoo thermal ruaj khov thiab tuaj yeem siv tau ntawm qhov kub.
4. Tshuaj lom neeg
Zirconium hydroxideyog ib yam khoom alkaline uas tuaj yeem hnov mob nrog cov acids los tsim cov ntsev ua kua thiab dej. Piv txwv li,Zirconium hydroxidereacts nrog hydrochloric acid los tsimzirconium chloridethiab dej:
ZR (OH) 4 + 4HCL → ZRLL4 + 4H2O
Zirconium hydrofide kuj tseem tuaj yeem hnov cuam tshuam nrog lwm cov hlau ions los ua cov precipitates. Piv txwv li, thaum aZirconium hydroxidedaws cov tshuaj tiv thaiv nrog ammonium ntsev, ib tug dawbZirconium hydroxidenag lossis daus yog tsim tawm:
Zr (Oh) 4 + 4NH4 + → zr (AH) 4 4NHNH4
5. Thov
5.1 catalysts
Zirconium hydroxideMuaj ntau cov kev siv hauv thaj teb catalysts. Nws tuaj yeem raug siv ua catalyst hauv liaj teb xws li kev ua roj av, tshuaj lom neeg, thiab kev tiv thaiv ib puag ncig.Zirconium hydroxideCatalysts muaj kev ua haujlwm siab thiab xaiv, uas tuaj yeem txhawb kev cov tshuaj tiv thaiv thiab txhim kho cov tshuaj purity ntawm cov khoom.
5.2 Cov Khoom Siv Ceramic
Zirconium hydroxidetseem muaj dav siv nyob rau hauv kev npaj ntawm cov ntaub ntawv ceramic. Vim nws lub siab melting taw tes thiab kub kuj tsis kam,Zirconium hydroxideYuav siv tau los npaj cov ntaub ntawv ntau tshaj plaws, xws li cov khoom siv regractory thiab thermal teeb meem txheej txheej. Ntxiv rau,Zirconium hydroxideKuj tseem tuaj yeem txhim kho cov khoom siv me me thiab coj kev tiv thaiv ntawm cov khoom siv ceramic.
5.3 Kev Rhoedical
Zirconium hydroxideKuj tseem muaj cov ntawv thov tseem ceeb hauv phau ntawv biomedical. Nws tuaj yeem siv los npaj cov pob txha ua thiab cov ntaub ntawv kho hniav, xws li cov pob qij txha ua kom zoo nkauj thiab cov hniav cuav. Vim nws zoo heev biocompatibility thiab kev ua haujlwm roj ntsha,Zirconium hydroxidetuaj yeem khi zoo nrog tib neeg cov nqaij, txo tus neeg mob thiab tsis xis nyob.
6. Kev ruaj ntseg
Zirconium hydroxidefeem ntau yog qhov sib txuas zoo. Txawm li cas los xij, vim nws alkalinity,Zirconium hydroxidetuaj yeem ua rau kev voos rau ntawm daim tawv nqaij thiab qhov muag. Yog li ntawd, thaum sivZirconium hydroxide, kev tiv thaiv tsim nyog tiv thaiv yuav tsum tau coj, xws li hnav hnab looj tes thiab goggles.
Ntxiv rau,Zirconium hydroxidekuj muaj qee yam toxicity. Thaum siv thiab tuavZirconium hydroxide, Nws yog ib qho tseem ceeb kom tsis txhob nqus plua plav lossis cov kev daws teeb meem los tiv thaiv kev puas tsuaj rau lub tshuab ua pa thiab lub plab zom mov.
7. Ntsiab lus
Zirconium hydroxideyog ib qho tseem ceeb inorganic compound nrog cov mis nyujZr (huag) 4Cov. Nws muaj ntau cov kev thov tseem ceeb, xws li catalysts, cov khoom siv ceramic, thiab cov teb biomedical.Zirconium hydroxideMuaj lub cev zoo thiab tshuaj chemical thiab tuaj yeem siv rau hauv cov pa taws kub thiab acidic ib puag ncig. Txawm li cas los xij, thaum siv thiab uaZirconium hydroxide, saib xyuas yuav tsum tau them rau nws cov alkalinity thiab lom kom paub tseeb. Los ntawm kev nkag mus tob tob txog cov khoom thiab cov ntawv thov ntawmZirconium hydroxide, ib qho tuaj yeem siv nws cov txiaj ntsig zoo thiab pab txhawb rau kev txhim kho cov teb.
