2. Ilana

Awọn molikula agbekalẹ tiZirconium hydroxide isZr (OH) 4, eyiti o jẹ ti ion zirconium kan (Zr4+) ati awọn ions hydroxide mẹrin (OH -). Ni awọn ri to ipinle, awọn be tiZirconium hydroxideti wa ni akoso nipasẹ ionic bonds laarin zirconium ions ati hydroxide ions. Awọn idiyele ti o dara ti awọn ions zirconium ati idiyele odi ti awọn ions hydroxide ṣe ifamọra ara wọn, ti o n ṣe ipilẹ okuta mọto.

3. Awọn ohun-ini ti ara

Zirconium hydroxidejẹ funfun ti o lagbara ti o dabi erupẹ tabi awọn patikulu ni irisi. Iwọn rẹ jẹ nipa 3.28 g/cm ³, aaye yo jẹ isunmọ 270 ° C.Zirconium hydroxidejẹ fere insoluble ninu omi ni yara otutu, ṣugbọn tiotuka ni acids. Solubility rẹ pọ si pẹlu ilosoke ti iwọn otutu.Zirconium hydroxideni iduroṣinṣin igbona to dara ati pe o le ṣee lo ni awọn iwọn otutu giga.

4. Awọn ohun-ini kemikali

Zirconium hydroxidejẹ ohun elo ipilẹ ti o le fesi pẹlu awọn acids lati gbe awọn iyọ ati omi ti o baamu. Fun apere,Zirconium hydroxidefesi pẹlu hydrochloric acid lati gbe awọnkiloraidi zirconiumati omi:

Zr (OH) 4+4HCl → ZrCl4+4H2O

Zirconium hydroxide tun le fesi pẹlu awọn ions irin miiran lati dagba awọn precipitates. Fun apẹẹrẹ, nigbati aZirconium hydroxideojutu reacts pẹlu ammonium iyọ, kan funfunZirconium hydroxideojoro ti wa ni ipilẹṣẹ:

Zr (OH) 4+4NH4+→ Zr (OH) 4 · 4NH4

5. Ohun elo

5.1 ayase

Zirconium hydroxideni o ni kan jakejado ibiti o ti ohun elo ni awọn aaye ti ayase. O le ṣee lo bi ayase ni awọn aaye bii sisẹ epo, iṣelọpọ kemikali, ati aabo ayika.Zirconium hydroxideayase ni ga aṣayan iṣẹ-ṣiṣe ati selectivity, eyi ti o le se igbelaruge awọn lenu ati ki o mu awọn ti nw ti awọn ọja.

5.2 Awọn ohun elo seramiki

Zirconium hydroxidetun jẹ lilo pupọ ni igbaradi awọn ohun elo seramiki. Nitori aaye yo giga rẹ ati resistance otutu giga,Zirconium hydroxidele ṣee lo lati ṣeto awọn ohun elo seramiki ti o ni iwọn otutu, gẹgẹbi awọn ohun elo ifasilẹ ati awọn ideri idena igbona. Ni afikun,Zirconium hydroxidetun le ṣe ilọsiwaju awọn ohun-ini ẹrọ ati wọ resistance ti awọn ohun elo seramiki.

5.3 Biomedical aaye

Zirconium hydroxidetun ni awọn ohun elo pataki ni aaye biomedical. O le ṣee lo lati ṣeto awọn egungun atọwọda ati awọn ohun elo ehín, gẹgẹbi awọn isẹpo atọwọda ati awọn ifibọ ehín. Nitori ibamu biocompatibility ti o dara julọ ati iṣẹ ṣiṣe ti ibi,Zirconium hydroxidele dipọ daradara pẹlu awọn ara eniyan, dinku irora alaisan ati aibalẹ.

6. Aabo

Zirconium hydroxideni gbogbo a jo ailewu yellow. Sibẹsibẹ, nitori ipilẹ rẹ,Zirconium hydroxidele fa irritation si awọ ara ati oju. Nitorina, nigba liloZirconium hydroxide, awọn igbese aabo ti o yẹ yẹ ki o mu, gẹgẹbi wọ awọn ibọwọ ati awọn goggles.

Ni afikun,Zirconium hydroxidetun ni awọn majele ti. Nigba lilo ati mimuZirconium hydroxide, o ṣe pataki lati yago fun eruku ifasimu tabi awọn ojutu lati ṣe idiwọ ibajẹ si awọn ọna atẹgun ati ti ounjẹ.

7. Lakotan

Zirconium hydroxidejẹ ẹya pataki inorganic yellow pẹlu awọn kemikali agbekalẹZr (OH) 4. O ni ọpọlọpọ awọn ohun elo pataki, gẹgẹbi awọn ayase, awọn ohun elo seramiki, ati awọn aaye biomedical.Zirconium hydroxideni awọn ohun-ini ti ara ati kemikali ti o dara ati pe o le ṣee lo ni iwọn otutu giga ati awọn agbegbe ekikan. Sibẹsibẹ, nigba lilo ati processingZirconium hydroxide, Ifarabalẹ yẹ ki o san si alkalinity rẹ ati majele lati rii daju aabo. Nipa nini oye ti o jinlẹ ti awọn ohun-ini ati awọn ohun elo tiZirconium hydroxide, ọkan le dara lo awọn anfani rẹ ati ki o ṣe alabapin si idagbasoke awọn aaye ti o jọmọ.
