I-Tricalcium phosphate (ebizwa ngokuthi i-TCP) yaziwa nangokuthi i-calcium phosphate, iyikristalu emhlophe noma i-amorphous powder.Kunezinhlobo eziningi ze-crystal transition, ezihlukaniswe ngokuyinhloko zibe izinga lokushisa eliphansi β-isigaba (β-TCP) kanye nokushisa okuphezulu α-phase (α-TCP).Izinga lokushisa lokushintsha kwesigaba ngu-1120 ℃-1170 ℃.

Igama lekhemikhali: i-tricalcium phosphate

Isibizo: i-calcium phosphate

Ifomula yemolekyuli: Ca3(P04)2

Isisindo se-molecule: 310.18

CAS: 7758-87-4

Izici ezingokomzimba

Ukubukeka kanye nezakhiwo: ezimhlophe, ezingenaphunga, ikristalu enganambitheki noma i-amorphous powder.

Iphuzu elincibilikayo (℃): 1670

I-Solubility: ayincibiliki emanzini, ayincibiliki ku-ethanol, i-acetic acid, inyibilika ku-asidi.

Isigaba sokushisa esiphezulu se-α siyingxenye yesistimu ye-monoclinic, ukuminyana okuhlobene yi-2.86 g / cm3;Uhlobo lwezinga lokushisa eliphansi elingu-β lungokwesistimu yekristalu eyi-hexagonal futhi ukuminyana kwayo okuhlobene ngu-3.07 g/cm3.

Ukudla

I-Tricalcium phosphate iyisivikeli sezakhi eziphephile, esifakwa ikakhulukazi ekudleni ukuze kuqinise ukuthathwa kwe-calcium, ingasetshenziswa futhi ukuvimbela ukuntuleka kwe-calcium noma inkinga enempilo ebangelwa ukushoda kwe-calcium.Ngesikhathi esifanayo, i-tricalcium phosphate ingasetshenziswa futhi njenge-anti-caking agent, isilawuli senani le-PH, i-buffer nokunye.Uma isetshenziswa ekudleni, ivame ukusetshenziswa kufulawa i-anti-caking agent (i-dispersant), i-milk powder, i-candy, i-pudding, i-seasoning, izithasiselo zenyama, izithasiselo zokucwenga amafutha ezilwane, ukudla kwemvubelo, njll.

I-Microencapsulated tricalcium phosphate, omunye wemithombo ye-calcium yomzimba womuntu, iwuhlobo lomkhiqizo we-calcium osebenzisa i-tricalcium phosphate njengempahla eluhlaza ngemva kokugaywa kwe-ultra-fine, bese imbozwa nge-lecithin ibe ama-microcapsules anobubanzi obungama-micrometer angu-3-5. .

Ngaphezu kwalokho, i-tricalcium phosphate, njengomthombo wansuku zonke we-calcium, inenzuzo ngaphezu kwezinye izithako ze-calcium ekunikezeni kokubili i-calcium ne-phosphorus.Ukugcina ibhalansi phakathi kwe-calcium ne-phosphorus emzimbeni kubalulekile ngoba womabili amaminerali abalulekile ekwakhekeni kwamathambo.Ngakho-ke uma le bhalansi ingenakufezeka, kuvame ukuba nzima ukufeza umphumela oyifunayo we-calcium supplementation.

Ezokwelapha

I-Tricalcium phosphate iyinto efanelekile yokulungisa nokushintshwa kwezicubu eziqinile zomuntu ngenxa yokuhambisana kwayo okuhle kwezinto eziphilayo, ukusebenza kahle kwezinto eziphilayo kanye nokuwohloka kwemvelo.Kuye kwaqashelwa kakhulu emkhakheni wobunjiniyela be-biomedical.I-α-tricalcium phosphate, i-β-tricalcium phosphate, ivame ukusetshenziswa kwezokwelapha.I-β Tricalcium phosphate yakhiwe ngokuyinhloko i-calcium ne-phosphorus, ukwakheka kwayo kufana nezingxenye ezingaphili ze-matrix yamathambo, futhi ibopha kahle emathanjeni.

Amaseli ezilwane noma omuntu angakhula, ahlukanise futhi akhiqize kabusha ngokujwayelekile ku-β-tricalcinum phosphate material.Inani elikhulu lezifundo zokuhlola lifakazela i-β-tricalcium phosphate, engenakho ukusabela okubi, akukho ukusabela kokwenqaba, akukho ukusabela okunobuthi okunamandla, akukho mkhuba wokungezwani komzimba.Ngakho-ke, i-β Tricalcium phosphate ingasetshenziswa kabanzi ekuhlanganiseni kwamalunga nomgogodla, izitho, ukuhlinzwa ngomlomo kanye ne-maxillofacial, ukuhlinzwa, nokugcwalisa imigodi ye-periodontal.

Olunye uhlelo lokusebenza:

esetshenziswa ekwenzeni ingilazi ye-opal, i-ceramic, upende, i-mordant, imithi, umanyolo, isithasiselo sokudla kwezilwane, i-ejenti yokucacisa isiraphu, i-plastic stabilizer, njll.
