Iyini i-zirconium hydroxide?

1. Isingeniso

I-Zirconium hydroxideiyinhlanganisela ye-inorganic ne-chemical formulaZr (OH) 4. Yakhiwa ion zirconium (Zr4+) kanye ion hydroxide (OH -).I-Zirconium hydroxideiqinile emhlophe encibilika kuma-asidi kodwa ayincibiliki emanzini. Inezinhlelo zokusebenza eziningi ezibalulekile, njengama-catalysts, izinto zokwakha ze-ceramic, nezinkambu ze-biomedical.Isiqephu: 14475-63-9;12688-15-2

2. Isakhiwo

Ifomula ye-molecular ofI-Zirconium hydroxide isZr (OH) 4, eyakhiwe ion eyodwa ye-zirconium (Zr4+) kanye nama-ion amane e-hydroxide (OH -). Esimeni esiqinile, ukwakheka kweI-Zirconium hydroxideyakhiwe ngamabhondi e-ionic phakathi kwe-zirconium ions nama-ion hydroxide. Ukushaja okuhle kwama-ion e-zirconium kanye nokushaja okungalungile kwama-ion we-hydroxide kudonselana, kwakha isakhiwo se-crystal esizinzile.

3. Izinto ezibonakalayo

I-Zirconium hydroxideiqinile emhlophe efana nempushana noma izinhlayiya ngokubukeka. Ukuminyana kwayo kucishe kube ngu-3.28 g/cm ³, Indawo yokuncibilika icishe ibe ngu-270 ° C.I-Zirconium hydroxideicishe ingancibiliki emanzini ekamelweni lokushisa, kodwa incibilika kuma-asidi. Ukunyibilika kwayo kuyanda ngokwanda kwezinga lokushisa.I-Zirconium hydroxideinokusimama okuhle kokushisa futhi ingasetshenziswa emazingeni okushisa aphezulu.

4. Izakhiwo zamakhemikhali

I-Zirconium hydroxideiyi-alkaline ekwazi ukusabela nge-acids ukukhiqiza usawoti ohambisanayo namanzi. Ngokwesibonelo,I-Zirconium hydroxideisabela nge-hydrochloric acid ukuze ikhiqizei-zirconium chloridenamanzi:

I-Zr (OH) 4+4HCl → ZrCl4+4H2O

I-Zirconium hydroxide nayo ingasabela namanye ama-ion ensimbi ukuze yakhe imvula. Ngokwesibonelo, lapho aI-Zirconium hydroxideIsixazululo sisabela ngosawoti we-ammonium, umhlopheI-Zirconium hydroxidei-precipitate iyakhiqizwa:

Zr (OH) 4+4NH4+→ Zr (OH) 4 · 4NH4

5. Isicelo

5.1 Ama-Catalysts

I-Zirconium hydroxideinezinhlobonhlobo zezicelo emkhakheni wama-catalysts. Ingasetshenziswa njenge-catalyst emikhakheni efana ne-petroleum processing, chemical synthesis, nokuvikelwa kwemvelo.I-Zirconium hydroxideama-catalyst anomsebenzi ophezulu kanye nokukhetha, okungakhuthaza ukusabela futhi kuthuthukise ukuhlanzeka komkhiqizo.

5.2 Izinto Zobumba

I-Zirconium hydroxideibuye isetshenziswe kabanzi ekulungiseleleni izinto ze-ceramic. Ngenxa yezinga layo eliphezulu lokuncibilika kanye nokumelana nezinga lokushisa eliphezulu,I-Zirconium hydroxideingasetshenziswa ukulungisa izinto ze-ceramic ezisezingeni eliphezulu, njengezinto eziphikisayo kanye nezingubo zokuvimbela ezishisayo. Ngaphezu kwalokho,I-Zirconium hydroxideingabuye ithuthukise izakhiwo zemishini futhi igqoke ukumelana kwezinto ze-ceramic.

5.3 Inkambu ye-Biomedical

I-Zirconium hydroxidefuthi inezinhlelo zokusebenza ezibalulekile emkhakheni we-biomedical. Ingasetshenziselwa ukulungisa amathambo okwenziwa kanye nezinto zamazinyo, njengamalunga okwenziwa kanye nokufakelwa kwamazinyo. Ngenxa ye-biocompatibility yayo enhle kakhulu kanye nomsebenzi we-biological,I-Zirconium hydroxideingabopha kahle nezicubu zomuntu, inciphise ubuhlungu besiguli nokungakhululeki.

6. Ezokuphepha

I-Zirconium hydroxidengokuvamile iyinhlanganisela ephephile uma kuqhathaniswa. Kodwa-ke, ngenxa ye-alkalinity yayo.I-Zirconium hydroxidekungabangela ukucasuka esikhumbeni nasemehlweni. Ngakho-ke, lapho usebenzisaI-Zirconium hydroxide, kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu ​​nezibuko.

Ngaphezu kwalokho,I-Zirconium hydroxidefuthi inobuthi obuthile. Lapho usebenzisa futhi uphathaI-Zirconium hydroxide, kubalulekile ukugwema ukuhogela uthuli noma izixazululo zokuvimbela ukulimala kwezinhlelo zokuphefumula nezokugaya.

7. Isifinyezo

I-Zirconium hydroxideiyinhlanganisela ebalulekile ye-inorganic kanye nefomula yamakhemikhaliZr (OH) 4. Inezinhlelo zokusebenza eziningi ezibalulekile, njengama-catalysts, izinto zokwakha ze-ceramic, nezinkambu ze-biomedical.I-Zirconium hydroxideinezakhiwo ezinhle zomzimba namakhemikhali futhi ingasetshenziswa ezindaweni ezishisayo nezine-acidic. Nokho, lapho usebenzisa futhi processingI-Zirconium hydroxide, ukunakwa kufanele kukhokhwe ku-alkalinity yayo kanye nobuthi ukuze kuqinisekiswe ukuphepha. Ngokuthola ukuqonda okujulile kwezakhiwo kanye nokusetshenziswa kweI-Zirconium hydroxide, umuntu angasebenzisa kangcono izinzuzo zayo futhi abambe iqhaza ekuthuthukisweni kwezinkambu ezihlobene.
