He aha ka zirconium hydroxide?

1. Hoʻolauna

Zirconium hydroxidehe pūhui kino ʻole me ke ʻano kemikaZr (OH) 4. Aia ia me nā ion zirconium (Zr4+) a me nā ion hydroxide (OH -).Zirconium hydroxidehe paʻa keʻokeʻo hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He nui nā noi koʻikoʻi, e like me nā catalysts, nā mea seramika, a me nā kahua biomedical.Ka helu: 14475-63-9;12688-15-2

2. Kapili

ʻO ke kumu molekala oZirconium hydroxide isZr (OH) 4, i haku ʻia me hoʻokahi ion zirconium (Zr4+) a me ʻehā ion hydroxide (OH -). Ma ke kūlana paʻa, ke ʻano oZirconium hydroxideua hana ʻia e nā paʻa ionic ma waena o nā ion zirconium a me nā ion hydroxide. ʻO ka hoʻopiʻi maikaʻi o nā ion zirconium a me ka hoʻopiʻi maikaʻi ʻole o nā ion hydroxide e huki kekahi i kekahi, e hana ana i kahi ʻano aniani paʻa.

3. Na waiwai kino

Zirconium hydroxidehe paʻa keʻokeʻo e like me ka pauda a i ʻole nā ​​ʻāpana i ka nānā aku. ʻO kona mānoanoa ma kahi o 3.28 g/cm ³, ʻO ka helu heheʻe ma kahi o 270 ° C.Zirconium hydroxideʻaneʻane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ka wela lumi, akā hiki ke hoʻoheheʻe ʻia i loko o nā waikawa. Piʻi kona solubility me ka piʻi ʻana o ka mahana.Zirconium hydroxidemaikaʻi ka paʻa wela a hiki ke hoʻohana ʻia i nā wela kiʻekiʻe.

4. Nā waiwai kemika

Zirconium hydroxidehe mea alkaline hiki ke hoʻopili me nā ʻakika e hana i nā paʻakai a me ka wai. ʻo kahi laʻana,Zirconium hydroxidehoʻopili me ka waika hydrochloric e hana aizirconium chloridea me ka wai:

Zr (OH) 4+4HCl → ZrCl4+4H2O

Hiki i ka Zirconium hydroxide ke hoʻopili pū me nā ion metala ʻē aʻe e hana i nā precipitates. Eia kekahi laʻana, i ka wā aZirconium hydroxidehoʻopili ka hopena me nā paʻakai ammonium, kahi keʻokeʻoZirconium hydroxidehana ʻia ka ehu:

Zr (OH) 4+4NH4+→ Zr (OH) 4 · 4NH4

5. Noi

5.1 Nā mea hoʻoheheʻe

Zirconium hydroxideloaʻa i kahi ākea o nā noi ma ke kahua o nā catalysts. Hiki ke hoʻohana ʻia ma ke ʻano he catalyst i nā kula e like me ka hoʻoili ʻana i ka petroleum, synthesis chemical, a me ka pale ʻana i ke kaiapuni.Zirconium hydroxidenā catalysts i ka hana kiʻekiʻe a me ke koho, hiki ke hoʻoikaika i ka hopena a hoʻomaikaʻi i ka maʻemaʻe o ka huahana.

5.2 Mea Hana Keramika

Zirconium hydroxidehoʻohana nui ʻia i ka hoʻomākaukau ʻana i nā mea seramika. Ma muli o kona kiʻekiʻe heheʻe a me ke kūpaʻa wela kiʻekiʻe,Zirconium hydroxidehiki ke hoʻohana ʻia e hoʻomākaukau i nā mea seramika kiʻekiʻe, e like me nā mea refractory a me nā pale pale wela. Kahi mea hou aʻe,Zirconium hydroxidehiki nō hoʻi ke hoʻomaikaʻi i nā waiwai mechanical a me ka pale ʻana o nā mea seramika.

5.3 kahua biomedical

Zirconium hydroxidehe mau noi koʻikoʻi nō hoʻi i ka ʻoihana biomedical. Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā iwi artificial a me nā mea niho, e like me nā hui a me nā implants niho. Ma muli o kāna biocompatibility maikaʻi loa a me ka hana biological,Zirconium hydroxidehiki ke hoʻopaʻa maikaʻi me nā ʻiʻo kanaka, e hōʻemi ana i ka ʻeha a me ka ʻeha.

6. Palekana

Zirconium hydroxideʻO ka maʻamau he hui palekana. Eia naʻe, ma muli o kona alkalinity,Zirconium hydroxidehiki ke hoʻonāukiuki i ka ʻili a me nā maka. No laila, i ka wā e hoʻohana aiZirconium hydroxide, pono e lawe ʻia nā ʻano pale kūpono, e like me ke komo ʻana i nā mīkina lima a me nā maka maka.

Kahi mea hou aʻe,Zirconium hydroxideloaʻa kekahi ʻona. I ka hoʻohana ʻana a me ka lawelawe ʻanaZirconium hydroxide, he mea nui e pale aku i ka inhale o ka lepo a i ʻole nā ​​mea hoʻonā no ka pale ʻana i ka pōʻino i ka hanu a me nā ʻōnaehana digestive.

7. Hōʻuluʻulu manaʻo

Zirconium hydroxidehe hui anoano ko'iko'i me ke kinikiniZr (OH) 4. He nui nā noi koʻikoʻi, e like me nā catalysts, nā mea seramika, a me nā kahua biomedical.Zirconium hydroxideloaʻa i nā waiwai kino a me nā kemika maikaʻi a hiki ke hoʻohana ʻia i nā wahi wela a me ka ʻakika. Eia naʻe, i ka hoʻohana ʻana a me ka hana ʻanaZirconium hydroxide, pono e nānā i kona alkalinity a me nā meaʻawaʻawa e hōʻoia i ka palekana. Ma ka loaʻa ʻana o ka ʻike hohonu o nā waiwai a me nā noi oZirconium hydroxide, hiki i kekahi ke hoʻohana maikaʻi i kona mau pono a kōkua i ka hoʻomohala ʻana i nā kahua pili.
