ʻO Tricalcium phosphate (i kapa ʻia ʻo TCP) ua ʻike ʻia hoʻi ʻo ia he calcium phosphate, he kristal keʻokeʻo a he pauka amorphous paha. Nui nā ʻano o ka hoʻololi kristal, i māhele nui ʻia i ka β-phase haʻahaʻa (β-TCP) a me ka α-phase wela kiʻekiʻe (α-TCP). ʻO ka mahana hoʻololi pae he 1120℃-1170℃.

Inoa kemika: tricalcium phosphate

ʻAi kapa ʻia: calcium phosphate

ʻO ke ʻano molekole: Ca3(P04)2

Kaumaha molekole: 310.18

CAS: 7758-87-4

Nā waiwai kino

ʻAno a me nā waiwai: keʻokeʻo, ʻala ʻole, aniani ʻono ʻole a pauka amorphous.

Wahi hoʻoheheʻe (℃): 1670

Solubility: hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol, ka waikawa acetic, hiki ke hoʻoheheʻe ʻia i ka waikawa.

ʻO ke ʻano wela kiʻekiʻe o ka pae α no ka ʻōnaehana monoclinic, ʻo ka nui pili he 2.86 g/cm3; ʻO ke ʻano wela haʻahaʻa o ka pae β no ka ʻōnaehana kristal hexagonal a ʻo kona nui pili he 3.07 g/cm3.

Meaʻai

He mea hoʻoikaika palekana ka Tricalcium phosphate, i hoʻohui nui ʻia i ka meaʻai e hoʻoikaika i ka lawe ʻana o ka calcium, hiki ke hoʻohana ʻia e pale i ka hemahema o ka calcium a i ʻole ka pilikia olakino i hoʻokumu ʻia e ka hemahema o ka calcium. I ka manawa like, hiki ke hoʻohana ʻia ka tricalcium phosphate ma ke ʻano he mea anti-caking agent, mea hoʻoponopono waiwai PH, buffer a pēlā aku. Ke hoʻohana ʻia i ka meaʻai, hoʻohana pinepine ʻia ia i ka mea anti-caking agent (dispersant), ka pauka waiū, nā mea ʻono, ka pudding, nā mea ʻala, nā mea hoʻohui ʻiʻo, nā mea hoʻohui hoʻomaʻemaʻe ʻaila holoholona, ​​​​​​meaʻai hū, a pēlā aku.

ʻO ka microencapsulated tricalcium phosphate, kekahi o nā kumu calcium no ke kino o ke kanaka, he ʻano huahana calcium ia e hoʻohana ana i ka tricalcium phosphate ma ke ʻano he mea maka ma hope o ka wili ʻana i ka wili maikaʻi loa, a laila e hoʻopili ʻia me ka lecithin i loko o nā microcapsules me ke anawaena o 3-5 micrometers.

Eia kekahi, ʻo ka tricalcium phosphate, ma ke ʻano he kumu calcium i kēlā me kēia lā, he pono ia ma mua o nā mea hoʻohui calcium ʻē aʻe i ka hāʻawi ʻana i ka calcium a me ka phosphorus. He mea nui ka mālama ʻana i ke kaulike ma waena o ka calcium a me ka phosphorus i loko o ke kino no ka mea he mea nui nā minelala ʻelua no ka hoʻokumu ʻana o ka iwi. No laila, inā ʻaʻole hiki ke hoʻokō ʻia kēia kaulike, he mea paʻakikī pinepine ka hoʻokō ʻana i ka hopena i makemake ʻia o ka hoʻohui calcium.

Lapaʻau

He mea kūpono ka Tricalcium phosphate no ka hoʻoponopono a me ka hoʻololi ʻana i nā ʻiʻo paʻakikī o ke kanaka ma muli o kona biocompatibility maikaʻi, bioactivity a me ka biodegradation. Ua nānā pono ʻia ma ke kahua o ka ʻenekinia biomedical. Hoʻohana pinepine ʻia ka α-tricalcium phosphate, β-tricalcium phosphate, i ka lāʻau lapaʻau. ʻO ka β Tricalcium phosphate ka mea nui i haku ʻia me ka calcium a me ka phosphorus, ua like kona ʻano me nā ʻāpana inorganic o ka matrix iwi, a pili pono ia i ka iwi.

Hiki i nā ʻāpana holoholona a kanaka paha ke ulu, hoʻokaʻawale a hoʻohua hou ma ke ʻano maʻamau ma luna o ka mea β-tricalcinum phosphate. Ua hōʻoia ka nui o nā haʻawina hoʻokolohua i ka β-tricalcium phosphate, ʻaʻohe hopena maikaʻi ʻole, ʻaʻohe hopena hōʻole, ʻaʻohe hopena ʻawahia koke, ʻaʻohe hanana maʻi. No laila, hiki ke hoʻohana nui ʻia ka β Tricalcium phosphate i ka hui ʻana o nā hono a me nā iwi kuamoʻo, nā lālā, ke ʻoki waha a me ka maxillofacial, ke ʻoki kino, a me ka hoʻopiha ʻana i nā lua periodontal.

ʻO kekahi noi ʻē aʻe:

hoʻohana ʻia i ka hana ʻana o ke aniani opal, ka seramika, ka pena, ka mordant, ka lāʻau lapaʻau, ka mea hoʻoulu, ka mea hoʻohui hānai holoholona, ​​​​ka mea hoʻomālamalama syrup, ka mea hoʻopaʻa plastik, a pēlā aku.
