I-Tricalcium phosphate (ebizwa ngokuthi i-TCP) yaziwa nangokuthi i-calcium phosphate, iyikristalu emhlophe noma i-amorphous powder. Kunezinhlobo eziningi zokuguquka kwekristalu, ezihlukaniswe kakhulu zibe yi-β-phase yokushisa okuphansi (β-TCP) kanye ne-α-phase yokushisa okuphezulu (α-TCP). Izinga lokushisa lokuguquka kwesigaba lingu-1120℃-1170℃.

Igama lamakhemikhali: i-triccalcium phosphate

Igama elingaziwa: i-calcium phosphate

Ifomula yama-molecule: Ca3(P04)2

Isisindo sama-molecule: 310.18

I-CAS: 7758-87-4

Izakhiwo zomzimba

Ukubukeka kanye nezakhiwo: okumhlophe, okungenaphunga, okunekristalu okungenambitheki noma impuphu engenasimo.

Iphuzu lokuncibilika (℃): 1670

Ukuncibilika: akuncibiliki emanzini, akuncibiliki ku-ethanol, i-acetic acid, kuyancibilika ku-asidi.

Isigaba sohlobo lwe-α lokushisa eliphezulu singesohlelo lwe-monoclinic, ukuminyana okuhlobene kungu-2.86 g/cm3; Isigaba sohlobo lwe-β lokushisa okuphansi singesohlelo lwekristalu olunezinhlangothi eziyisithupha kanti ukuminyana kwalo okuhlobene kungu-3.07 g/cm3.

Ukudla

I-Tricalcium phosphate iyisithako esiphephile sezakhamzimba, esifakwa kakhulu ekudleni ukuqinisa ukungenisa i-calcium, singasetshenziswa futhi ukuvimbela ukuntuleka kwe-calcium noma inkinga enempilo ebangelwa ukuntuleka kwe-calcium. Ngesikhathi esifanayo, i-tricalcium phosphate ingasetshenziswa futhi njenge-anti-caking agent, i-PH value regulator, i-buffer njalo njalo. Uma isetshenziswa ekudleni, ivame ukusetshenziswa ku-flour anti-caking agent (dispersant), ubisi oluyimpuphu, amaswidi, i-pudding, izinongo, izithasiselo zenyama, izithasiselo zokuhlanza uwoyela wezilwane, ukudla kwemvubelo, njll.

I-microencapsulated tricalcium phosphate, omunye wemithombo ye-calcium emzimbeni womuntu, uhlobo lomkhiqizo we-calcium osebenzisa i-triccalcium phosphate njengezinto zokusetshenziswa ngemva kokugaya kahle kakhulu, bese uhlanganiswa ne-lecithin ibe ama-microcapsule anobubanzi obungama-micrometer angu-3-5.

Ngaphezu kwalokho, i-triccalcium phosphate, njengomthombo wansuku zonke we-calcium, inenzuzo ngaphezu kwezinye izithako ze-calcium ekuhlinzekeni kokubili i-calcium ne-phosphorus. Ukugcina ibhalansi phakathi kwe-calcium ne-phosphorus emzimbeni kubalulekile ngoba womabili amaminerali abalulekile ekwakhekeni kwamathambo. Ngakho-ke uma lokhu kulinganisela kungenzeki, kuvame ukuba nzima ukufeza umphumela ofiselekayo wokwengeza i-calcium.

Ezokwelapha

I-Tricalcium phosphate iyinto efanelekile yokulungisa nokufaka esikhundleni izicubu eziqinile zomuntu ngenxa yokuhambisana kahle kwezinto eziphilayo, ukusebenza kahle kwezinto eziphilayo kanye nokubola kwezinto eziphilayo. Iqashelwe kakhulu emkhakheni wobunjiniyela bezokwelapha. I-α-tricium phosphate, i-β-tricium phosphate, ivame ukusetshenziswa kwezokwelapha. I-β Tricalcium phosphate yakhiwe kakhulu nge-calcium ne-phosphorus, ukwakheka kwayo kufana nezingxenye ezingaphili ze-bone matrix, futhi ibopha kahle emathanjeni.

Amaseli ezilwane noma abantu angakhula, ahlukanise futhi azale ngokujwayelekile ezintweni ze-β-tricalcinum phosphate. Inani elikhulu lezifundo zokuhlola lifakazela i-β-tricalcium phosphate, engenazo iziphazamiso ezimbi, engenazo iziphazamiso zokwenqatshwa, engenazo iziphazamiso ezinobuthi obukhulu, engenazo izinto ezibangela ukungezwani komzimba. Ngakho-ke, i-β Tricalcium phosphate ingasetshenziswa kabanzi ekuhlanganiseni amalunga nomgogodla, izitho, ukuhlinzwa komlomo kanye nobuso obukhulu, ukuhlinzwa, kanye nokugcwalisa imigodi ye-periodontal.

Olunye uhlelo lokusebenza:

isetshenziswa ekwenziweni kwengilazi ye-opal, i-ceramic, upende, i-mordant, imithi, umanyolo, isithasiselo sokudla kwezilwane, i-syrup clarifying agent, i-plastic stabilizer, njll.
