Kodi zirconium hydroxide ndi chiyani?

1. Mawu Oyamba

Zirconium hydroxidendi organic pawiri ndi mankhwala chilinganizoZr (OH) 4. Amapangidwa ndi ayoni a zirconium (Zr4+) ndi ayoni a hydroxide (OH -).Zirconium hydroxidendi cholimba choyera chomwe chimasungunuka mu ma asidi koma osasungunuka m'madzi. Ili ndi ntchito zambiri zofunika, monga zopangira, zida za ceramic, ndi ma biomedical fields.Cas: 14475-63-9;12688-15-2

2. Kapangidwe

The molecular formula ofZirconium hydroxide isZr (OH) 4, yomwe imapangidwa ndi ion imodzi ya zirconium (Zr4 +) ndi ma ion hydroxide anayi (OH -). Mu chikhalidwe cholimba, kapangidwe kaZirconium hydroxideamapangidwa ndi ma ionic zomangira pakati pa ayoni zirconium ndi ayoni hydroxide. Malipiro abwino a ayoni a zirconium ndi ma ion a hydroxide amakopana wina ndi mnzake, ndikupanga mawonekedwe okhazikika a kristalo.

3. Zinthu zakuthupi

Zirconium hydroxidendi cholimba choyera chomwe chimafanana ndi ufa kapena tinthu ting'onoting'ono m'mawonekedwe. Kachulukidwe ake ndi pafupifupi 3.28 g/cm ³, Malo osungunuka ndi pafupifupi 270 ° C.Zirconium hydroxidepafupifupi sungunuka m'madzi kutentha firiji, koma sungunuka zidulo. Kusungunuka kwake kumawonjezeka ndi kuwonjezeka kwa kutentha.Zirconium hydroxideali ndi kukhazikika kwabwino kwa kutentha ndipo angagwiritsidwe ntchito pa kutentha kwakukulu.

4. Mankhwala katundu

Zirconium hydroxidendi mankhwala amchere omwe amatha kuchitapo kanthu ndi zidulo kuti apange mchere ndi madzi ofanana. Mwachitsanzo,Zirconium hydroxideimakhudzidwa ndi hydrochloric acid kuti ipangezirconiamu kloridendi madzi:

Zr (OH) 4+4HCl → ZrCl4+4H2O

Zirconium hydroxide imathanso kuchitapo kanthu ndi ayoni ena achitsulo kupanga ma precipitates. Mwachitsanzo, pamene aZirconium hydroxideyankho amachitira ndi ammonium salt, woyeraZirconium hydroxidempweya umapangidwa:

Zr (OH) 4+4NH4+→ Zr (OH) 4 · 4NH4

5. Kugwiritsa ntchito

5.1 Zothandizira

Zirconium hydroxideali ndi ntchito zosiyanasiyana m'munda wa catalysts. Itha kugwiritsidwa ntchito ngati chothandizira m'magawo monga kukonza mafuta, kaphatikizidwe ka mankhwala, komanso kuteteza chilengedwe.Zirconium hydroxidezothandizira ndi mkulu ntchito ndi selectivity, amene angalimbikitse anachita ndi kusintha chiyero cha mankhwala.

5.2 Zida za Ceramic

Zirconium hydroxideamagwiritsidwanso ntchito kwambiri pokonza zipangizo za ceramic. Chifukwa cha malo ake osungunuka komanso kutentha kwambiri,Zirconium hydroxideangagwiritsidwe ntchito pokonzekera zipangizo zadothi zotentha kwambiri, monga zipangizo zokanira ndi zokutira zotchinga kutentha. Kuphatikiza apo,Zirconium hydroxideIkhozanso kupititsa patsogolo makina ndi kuvala kukana kwa zipangizo za ceramic.

5.3 Gawo la Biomedical

Zirconium hydroxideilinso ndi zofunikira pazamankhwala azachipatala. Itha kugwiritsidwa ntchito popanga mafupa opangira mano ndi zida zamano, monga zolumikizira zopangira komanso zoyika mano. Chifukwa cha biocompatibility yake yabwino komanso ntchito zamoyo,Zirconium hydroxideimatha kumangirira bwino ndi minofu ya anthu, kuchepetsa ululu wa odwala komanso kusamva bwino.

6. Chitetezo

Zirconium hydroxidenthawi zambiri imakhala yotetezeka. Komabe, chifukwa cha alkalinity yake.Zirconium hydroxideangayambitse kuyabwa pakhungu ndi maso. Choncho, pamene ntchitoZirconium hydroxide, njira zodzitetezera ziyenera kuchitidwa, monga kuvala magolovesi ndi magalasi.

Kuphatikiza apo,Zirconium hydroxideilinso ndi kawopsedwe kena. Pamene mukugwiritsa ntchito ndi kusamaliraZirconium hydroxide, ndikofunikira kupewa kutulutsa fumbi kapena njira zothanirana ndi vuto la kupuma ndi kugaya chakudya.

7. Mwachidule

Zirconium hydroxidendi yofunika inorganic pawiri ndi chilinganizo mankhwalaZr (OH) 4. Ili ndi ntchito zambiri zofunika, monga zopangira, zida za ceramic, ndi ma biomedical fields.Zirconium hydroxideali ndi zinthu zabwino zakuthupi ndi zamankhwala ndipo amatha kugwiritsidwa ntchito potentha kwambiri komanso m'malo okhala acidic. Komabe, pamene ntchito ndi processingZirconium hydroxide, chidwi chiyenera kuperekedwa ku alkalinity yake ndi kawopsedwe kuonetsetsa chitetezo. Pakumvetsetsa mozama za katundu ndi ntchito zaZirconium hydroxide, munthu angagwiritse ntchito bwino ubwino wake ndikuthandizira pa chitukuko cha magawo okhudzana nawo.
