Yintoni i-zirconium hydroxide?

1. Intshayelelo

Zirconium hydroxideyi-inorganic compound kunye ne-chemical formulaIZr (OH) 4. Iqulethwe ion zirconium (Zr4 +) kunye ion hydroxide (OH -).Zirconium hydroxidesisiqina esimhlophe esinyibilika kwiiasidi kodwa ezinganyibiliki emanzini. Inemisebenzi emininzi ebalulekileyo, enje nge-catalysts, imathiriyeli ye-ceramic, kunye nemimandla ye-biomedical.Cas: 14475-63-9;12688-15-2

2. Isakhiwo

Ifomula yemolekyuli yeZirconium hydroxide isIZr (OH) 4, equlunqwe yi-ion ye-zirconium (i-Zr4 +) kunye nee-ion ezine ze-hydroxide (OH -). Kwimeko eqinileyo, isakhiwo seZirconium hydroxideyenziwe ngamabhondi e-ionic phakathi kwe-zirconium ion kunye ne-hydroxide ions. Intlawulo efanelekileyo ye-zirconium ions kunye nentlawulo embi ye-hydroxide ions itsala omnye komnye, yenza isakhiwo se-crystal esizinzile.

3. Iimpawu ezibonakalayo

Zirconium hydroxidesisiqina esimhlophe esifana nomgubo okanye amasuntswana ngenkangeleko. Ubuninzi bayo bumalunga ne-3.28 g/cm ³, Indawo yokunyibilika imalunga ne-270 ° C.Zirconium hydroxideiphantse yanganyibiliki emanzini kubushushu begumbi, kodwa iyanyibilika kwiiasidi. Ukunyibilika kwayo kuyanda ngokunyuka kwamaqondo obushushu.Zirconium hydroxideinozinzo oluhle lwe-thermal kwaye ingasetyenziswa kumaqondo obushushu aphezulu.

4. Iimpawu zeMichiza

Zirconium hydroxideyinto yealkaline enokuthi isebenze ngeeasidi ukuvelisa iityuwa ezihambelanayo kunye namanzi. Umzekelo,Zirconium hydroxideisabela nge-hydrochloric acid ukuvelisai-zirconium chloridekunye namanzi:

I-Zr (OH) 4+4HCl → ZrCl4+4H2O

I-Zirconium hydroxide nayo inokusabela kunye nezinye i-ion zetsimbi ukwenza i-precipitates. Umzekelo, xa aZirconium hydroxideisisombululo siphendula ngeetyuwa ze-ammonium, ezimhlopheZirconium hydroxideimvula iyenziwa:

Zr (OH) 4+4NH4+→ Zr (OH) 4 · 4NH4

5. Isicelo

5.1 IiCatalysts

Zirconium hydroxideinoluhlu olubanzi lwezicelo kwintsimi ye-catalysts. Ingasetyenziswa njenge-catalyst kwimimandla efana ne-petroleum processing, i-chemical synthesis, kunye nokukhusela okusingqongileyo.Zirconium hydroxidei-catalysts inomsebenzi ophezulu kunye nokukhetha, okunokukhuthaza ukusabela kunye nokuphucula ukucoceka kwemveliso.

5.2 Izinto zeCeramic

Zirconium hydroxideisetyenziswa ngokubanzi ekulungiseleleni izinto ze-ceramic. Ngenxa yeqondo eliphezulu lokunyibilika kunye nokumelana nobushushu obuphezulu,Zirconium hydroxideingasetyenziselwa ukulungiselela izixhobo ze-ceramic zobushushu obuphezulu, njengezinto eziphikisayo kunye neengubo zokuthintela i-thermal. Ukwengeza,Zirconium hydroxideinokuphucula iipropathi zoomatshini kunye nokumelana nokunxiba kwezixhobo ze-ceramic.

5.3 Indawo yeBiomedical

Zirconium hydroxideKananjalo inezicelo ezibalulekileyo kwintsimi yebhayoloji. Ingasetyenziselwa ukulungisa amathambo okwenziwa kunye nezixhobo zamazinyo, ezifana namalungu okwenziwa kunye nokufakelwa kwamazinyo. Ngenxa ye-biocompatibility egqwesileyo kunye nomsebenzi webhayoloji,Zirconium hydroxideinokubopha kakuhle kunye nezicubu zomntu, ukunciphisa intlungu yesigulane kunye nokukhathazeka.

6. Ukhuseleko

Zirconium hydroxidengokuqhelekileyo yinto ekhuselekileyo ngokwentelekiso. Nangona kunjalo, ngenxa ye-alkalinity yayo.Zirconium hydroxidekunokubangela ukucaphuka kwesikhumba kunye namehlo. Ngoko ke, xa usebenzisaZirconium hydroxide, kufanele kuthathwe amanyathelo afanelekileyo okuzikhusela, njengokunxiba iiglavu neeglavu.

Ukwengeza,Zirconium hydroxidekananjalo inetyhefu ethile. Xa usebenzisa kunye nokuphathaZirconium hydroxide, kubalulekile ukuphepha ukuphefumula uthuli okanye izisombululo zokuthintela umonakalo kwiinkqubo zokuphefumula kunye nokugaya.

7. Isishwankathelo

Zirconium hydroxideyinto ebalulekileyo ye-inorganic compound kunye ne-chemical formulaIZr (OH) 4. Inemisebenzi emininzi ebalulekileyo, enje nge-catalysts, imathiriyeli ye-ceramic, kunye nemimandla ye-biomedical.Zirconium hydroxideinomzimba kunye neekhemikhali ezifanelekileyo kwaye inokusetyenziswa kwindawo yobushushu obuphezulu kunye ne-acidic. Nangona kunjalo, xa usebenzisa kunye nokusebenzaZirconium hydroxide, ingqalelo kufuneka ihlawulwe kwi-alkalinity yayo kunye netyhefu ukuqinisekisa ukhuseleko. Ngokufumana ukuqonda okunzulu kwiipropati kunye nokusetyenziswa kweZirconium hydroxide, umntu unokuzisebenzisa ngcono iingenelo zayo kwaye abe negalelo kuphuhliso lwemimandla enxulumeneyo.
