I-Tricalcium phosphate (ebizwa ngokuba yi-TCP) ikwabizwa ngokuba yi-calcium phosphate, yikristale emhlophe okanye i-amorphous powder.Kukho iintlobo ezininzi ze-crystal transition, eziye zahlulwe kakhulu kwiqondo lokushisa eliphantsi β-phase (β-TCP) kunye nokushisa okuphezulu kwe-α-phase (α-TCP).Ubushushu benguqu yesigaba yi-1120℃-1170℃.

Igama leKhemikhali: i-tricalcium phosphate

Isibizo: calcium phosphate

Ifomula yemolekyuli: Ca3(P04)2

Ubunzima bemolekyuli: 310.18

CAS: 7758-87-4

Iimpawu ezibonakalayo

Imbonakalo kunye neempawu: ezimhlophe, ezingenavumba, ikristale engenancasa okanye i-amorphous powder.

Indawo yokunyibilika (℃): 1670

Ukunyibilika: akunyibiliki emanzini, akunyibiliki kwi-ethanol, i-acetic acid, i-soluble kwi-asidi.

Uhlobo lobushushu obuphezulu α isigaba singokwenkqubo ye-monoclinic, ukuxinana kwe-2.86 g / cm3;Uhlobo oluphantsi lobushushu besigaba se-β sikwi-hexagonal crystal system kunye nokuxinana kwayo yi-3.07 g/cm3.

Ukutya

I-Tricalcium phosphate sisixhobo sokuqinisa izondlo esikhuselekileyo, esidityaniswe ikakhulu ekutyeni ukuqinisa ukuthathwa kwekhalsiyam, isenokusetyenziswa ukuthintela ukunqongophala kwekhalsiyam okanye ingxaki esempilweni ebangelwa kukunqongophala kwekhalsiyam.Kwangaxeshanye, i-tricalcium phosphate nayo ingasetyenziswa njenge-anti-caking agent, i-PH value regulator, i-buffer njalo njalo.Xa isetyenziswa ekutyeni, isetyenziswa ngokuqhelekileyo kumgubo we-anti-caking agent (i-dispersant), i-milk powder, i-candy, i-pudding, i-seasoning, izongezo zenyama, izongezelelo zokucoca i-oyile yezilwanyana, ukutya kwegwele, njl.

I-Microencapsulated tricalcium phosphate, enye yemithombo ye-calcium emzimbeni womntu, luhlobo lwemveliso ye-calcium esebenzisa i-tricalcium phosphate njengemathiriyeli ekrwada emva kokusila nge-ultra-fine, emva koko ifakwe i-lecithin kwii-microcapsules ezinobubanzi obuyi-3-5 micrometers. .

Ukongezelela, i-tricalcium phosphate, njengomthombo wemihla ngemihla we-calcium, inenzuzo ngaphezu kwezinye izongezo ze-calcium ekuboneleleni zombini i-calcium kunye ne-phosphorus.Ukugcina ibhalansi phakathi kwe-calcium kunye ne-phosphorus emzimbeni kubalulekile kuba zombini iiminerali zibalulekile ekwenzeni amathambo.Ke ukuba le bhalansi ayinakwenzeka, kuhlala kunzima ukufezekisa isiphumo esinqwenelekayo sokuxhaswa kwe-calcium.

Ezonyango

I-Tricalcium phosphate sisixhobo esifanelekileyo sokulungiswa kunye nokutshintshwa kwezicubu eziqinileyo zomntu ngenxa ye-biocompatibility yayo elungileyo, i-bioactivity kunye nokuguqulwa kwezinto eziphilayo.Kuye kwaqwalaselwa ngokucokisekileyo kwinkalo yobunjineli be-biomedical.I-α-tricalcium phosphate, i-β-tricalcium phosphate, isetyenziswa ngokuqhelekileyo kumayeza.β Tricalcium phosphate ubukhulu becala yenziwe ngecalcium kunye nephosphorus, ukubunjwa kwayo kuyafana namalungu e-inorganic ye-matrix yamathambo, kwaye ibophelela kakuhle emathanjeni.

Iiseli zezilwanyana okanye zomntu zinokukhula, zahlule kwaye zivelise kwakhona ngokuqhelekileyo kwimathiriyeli ye-β-tricalcinum phosphate.Inani elikhulu lophononongo lovavanyo lungqina i-β-tricalcium phosphate, engenachaphaza, akukho mpendulo yokwala, akukho mpendulo yityhefu ebukhali, akukho nto yala.Ngoko ke, i-β Tricalcium phosphate ingasetyenziswa ngokubanzi kwi-joint and spinal fusion, imilenze, utyando lomlomo kunye ne-maxillofacial, utyando, kunye nokuzalisa i-periodontal cavities.

Olunye usetyenziso:

isetyenziswe ekwenzeni iglasi ye-opal, i-ceramic, ipeyinti, i-mordant, iyeza, isichumisi, isongezo sokutya kwezilwanyana, i-arhente yokucacisa isiraphu, i-plastic stabilizer, njl.
