Nws muaj ntau yam kev siv tseem ceeb, xws li catalysts, ceramics, thiab biomedical teb.Cas: 14475-63-9; 12688-15-2
2. Qauv
Cov mis molecular ntawmZirconium hydroxide isZr (OH) 4, uas yog tsim los ntawm ib tug zirconium ion (Zr4 +) thiab plaub hydroxide ions (OH -). Nyob rau hauv lub xeev cov khoom, cov qauv ntawmZirconium hydroxideyog tsim los ntawm ionic bonds ntawm zirconium ions thiab hydroxide ions. Tus nqi zoo ntawm zirconium ions thiab cov nqi tsis zoo ntawm hydroxide ions nyiam ib leeg, tsim cov qauv siv lead ua ruaj khov.
3. Lub cev muaj zog
Zirconium hydroxideyog cov khoom dawb uas zoo li cov hmoov los yog cov khoom hauv qhov tsos. Nws qhov ceev yog li 3.28 g / cm³, lub melting point yog kwv yees li 270 ° C.Zirconium hydroxideNws yuav luag insoluble nyob rau hauv dej ntawm chav tsev kub, tab sis soluble nyob rau hauv acids. Nws solubility nce nrog qhov nce ntawm qhov kub thiab txias.Zirconium hydroxidemuaj thermal stability zoo thiab tuaj yeem siv rau qhov kub thiab txias.
4. Cov khoom siv tshuaj
Zirconium hydroxideyog ib yam khoom alkaline uas tuaj yeem cuam tshuam nrog cov kua qaub los tsim cov ntsev thiab dej sib xws. Piv txwv li,Zirconium hydroxidereacts nrog hydrochloric acid los tsimzirconium chloridethiab dej:
Zr (OH) 4+4HCl → ZrCl4+4H2O
Zirconium hydroxide kuj tuaj yeem hnov mob nrog lwm cov hlau ions los ua precipitates. Piv txwv li, thaum aZirconium hydroxidetshuaj reacts nrog ammonium ntsev, ib tug dawbZirconium hydroxideprecipitate yog generated:
Zr (OH) 4+4NH4+ → Zr (OH) 4 · 4NH4
5. Daim ntawv thov

Nws tuaj yeem siv los npaj cov pob txha thiab cov khoom siv kho hniav, xws li cov pob qij txha thiab cov hniav cog hniav. Vim nws zoo heev biocompatibility thiab lom lom,Zirconium hydroxidetuaj yeem khi zoo nrog tib neeg cov ntaub so ntswg, txo cov neeg mob mob thiab tsis xis nyob.
6. Kev ruaj ntseg
Zirconium hydroxidefeem ntau yog ib qho kev nyab xeeb zoo. Txawm li cas los xij, vim nws alkalinity,Zirconium hydroxidetuaj yeem ua rau khaus tawv nqaij thiab qhov muag. Yog li ntawd, thaum sivZirconium hydroxide, yuav tsum muaj kev tiv thaiv tsim nyog, xws li hnav hnab looj tes thiab tsom iav.
Ntxiv rau,Zirconium hydroxidekuj muaj qee yam toxicity. Thaum siv thiab tuavZirconium hydroxide, Nws yog ib qho tseem ceeb kom tsis txhob nqus cov plua plav lossis cov tshuaj tiv thaiv kom tsis txhob muaj kev puas tsuaj rau cov hlab ntsws thiab cov hnyuv.
7. Cov ntsiab lus
Zirconium hydroxideyog ib qho tseem ceeb inorganic compound nrog cov tshuaj formulaZr (OH) 4. Nws muaj ntau yam kev siv tseem ceeb, xws li catalysts, ceramics, thiab biomedical teb.Zirconium hydroxidemuaj lub cev zoo thiab tshuaj lom neeg thiab tuaj yeem siv rau hauv qhov kub thiab txias thiab acidic ib puag ncig. Txawm li cas los xij, thaum siv thiab uaZirconium hydroxide, xim yuav tsum tau them rau nws alkalinity thiab toxicity kom muaj kev nyab xeeb. Los ntawm kev nkag siab tob txog cov khoom thiab kev siv ntawmZirconium hydroxide, ib tus tuaj yeem siv nws cov txiaj ntsig zoo dua thiab pab txhawb rau kev txhim kho ntawm lwm yam kev lag luam.
