Tricalcium phosphate (inonzi TCP) inonziwo calcium phosphate, iri white crystal kana amorphous powder.Kune marudzi mazhinji ekuchinja kwekristaro, ayo anonyanya kukamurwa kuita yakaderera tembiricha β-phase (β-TCP) uye yakakwirira tembiricha α-phase (α-TCP).Iyo chikamu chekushandura tembiricha ndeye 1120 ℃-1170 ℃.

Zita remakemikari: tricalcium phosphate

Zita: calcium phosphate

Molecular formula: Ca3(P04)2

Molecular uremu: 310.18

CAS: 7758-87-4

Zvinhu zvenyama

Kuonekwa uye zvivakwa: chena, isina kunhuhwirira, isinganakidze kristaro kana amorphous poda.

Kunyungudika (℃): 1670

Solubility: isinganyungudika mumvura, isinganyunguriki mu ethanol, acetic acid, inonyungudika muasidhi.

High tembiricha mhando α chikamu ndeye monoclinic system, iyo hama density ndeye 2.86 g/cm3;Iyo yakaderera tembiricha yemhando β chikamu ndeye hexagonal crystal system uye hukama hwayo ndeye 3.07 g/cm3.

Zvokudya

Tricalcium phosphate inochengetedza kudya kunosimbisa, inonyanya kuwedzerwa muchikafu kusimbisa kudyiwa kwecalcium, inogona zvakare kushandiswa kudzivirira kushomeka kwecalcium kana dambudziko rine hutano rinokonzerwa nekushomeka kwecalcium.Panguva imwecheteyo, tricalcium phosphate inogonawo kushandiswa senge anti-caking agent, PH kukosha regulator, buffer uye zvichingodaro.Kana ichishandiswa mukudya, inowanzoshandiswa muupfu anti-caking agent (dispersant), mukaka poda, candy, pudding, seasoning, nyama yekuwedzera, mafuta emhuka anonatsa zvinowedzera, mbiriso chikafu, nezvimwe.

Microencapsulated tricalcium phosphate, imwe yecalcium masosi emuviri wemunhu, imhando yechigadzirwa checalcium chinoshandisa tricalcium phosphate seyakabikwa mushure mekuita zvekukuya kwekupedzisira, uyezve kuvharirwa nelecithin mumamicrocapsules ane dhayamita ye3-5 micrometer. .

Pamusoro pezvo, tricalcium phosphate, sesosi yezuva nezuva yecalcium, ine mukana pane mamwe ma supplements e calcium mukupa zvese zviri zviviri calcium ne phosphorus.Kuchengeta chiyero pakati pecalcium ne phosphorus mumuviri kwakakosha nekuti zvese zvicherwa zvakakosha pakuumbwa kwemapfupa.Saka kana chiyero ichi chikatadza kuitika, kazhinji zvinonetsa mukuwana mhedzisiro inodiwa ye calcium supplementation.

Medical

Tricalcium phosphate chinhu chakanakira kugadzirisa uye kutsiviwa kwenyama yakaoma yemunhu nekuda kweiyo yakanaka biocompatibility, bioactivity uye biodegradation.Yakabhadharwa zvakanyanya mumunda we biomedical engineering.α-tricalcium phosphate, β-tricalcium phosphate, inowanzoshandiswa mukurapa.β Tricalcium phosphate inonyanya kuumbwa necalcium uye phosphorus, kuumbwa kwayo kwakafanana neinorganic zvikamu zvebhonzo matrix, uye inosunga zvakanaka kubhonzo.

Maseru emhuka kana emunhu anogona kukura, kusiyanisa uye kubereka zvakajairika pane iyo β-tricalcinum phosphate zvinhu.Nhamba huru yezvidzidzo zvekuedza inoratidza β-tricalcium phosphate, isina maitiro akashata, isina kurambwa kuita, isina acute toxic reaction, hapana allergic phenomenon.Naizvozvo, β Tricalcium phosphate inogona kushandiswa zvakanyanya mukubatana uye spinal fusion, nhengo, nemuromo uye maxillofacial kuvhiyiwa, kuvhiya, uye kuzadza periodontal cavities.

Kumwe kushanda:

inoshandiswa mukugadzira opal girazi, ceramic, pendi, mordant, mushonga, fetiraiza, chikafu chemhuka chekuwedzera, sirasi inojekesa mumiriri, stabilizer yepurasitiki, nezvimwe.
