Tricalcium phosphate (yotchedwa TCP) imadziwikanso kuti calcium phosphate, ndi white crystal kapena amorphous powder.Pali mitundu yambiri ya kusintha kwa kristalo, yomwe imagawidwa makamaka kutentha kwa β-phase (β-TCP) ndi kutentha kwa α-phase (α-TCP).The gawo kusintha kutentha ndi 1120 ℃-1170 ℃.

Dzina la mankhwala: tricalcium phosphate

Dzina lina: calcium phosphate

Katunduyu: Ca3(P04)2

Molecular kulemera: 310.18

CAS: 7758-87-4

Thupi katundu

Maonekedwe ndi katundu: woyera, wopanda fungo, kristalo wosakoma kapena ufa wa amorphous.

Posungunuka (℃): 1670

Kusungunuka: kusungunuka m'madzi, kusungunuka mu ethanol, asidi asidi, kusungunuka mu asidi.

Kutentha kwamtundu wa α gawo ndi la monoclinic system, kuchulukana kwachibale ndi 2.86 g / cm3;Kutentha kwamtundu wa β gawo ndi kwa hexagonal crystal system ndipo kachulukidwe kake ndi 3.07 g/cm3.

Chakudya

Tricalcium phosphate ndi michere yotetezeka yolimbitsa thupi, makamaka yowonjezeredwa muzakudya kuti ikhale ndi calcium, itha kugwiritsidwanso ntchito kupewa kuchepa kwa calcium kapena vuto lathanzi lobwera chifukwa cha kuchepa kwa calcium.Nthawi yomweyo, tricalcium phosphate imatha kugwiritsidwanso ntchito ngati anti-caking agent, PH value regulator, buffer ndi zina zotero.Akagwiritsidwa ntchito pazakudya, amagwiritsidwa ntchito kwambiri mu ufa wotsutsa-caking wothandizira (dispersant), ufa wa mkaka, maswiti, pudding, zokometsera, zowonjezera za nyama, zowonjezera zowonjezera mafuta a nyama, chakudya cha yisiti, ndi zina zotero.

Microencapsulated tricalcium phosphate, imodzi mwa magwero a calcium m'thupi la munthu, ndi mtundu wa calcium phosphate yomwe imagwiritsa ntchito tricalcium phosphate ngati zopangira zopangira pambuyo pogaya kwambiri, kenako ndikukutidwa ndi lecithin kukhala ma microcapsules okhala ndi mainchesi 3-5. .

Kuonjezera apo, tricalcium phosphate, monga gwero la kashiamu tsiku ndi tsiku, ili ndi ubwino kuposa mankhwala ena a calcium popereka calcium ndi phosphorous.Kusunga bwino pakati pa kashiamu ndi phosphorous m’thupi n’kofunika chifukwa mcherewo ndi wofunika kwambiri kuti mafupa apangidwe.Chifukwa chake ngati izi sizingakwaniritsidwe, nthawi zambiri zimakhala zovuta kuti mukwaniritse zofunikira za calcium supplementation.

Zachipatala

Tricalcium phosphate ndi chinthu choyenera kukonzanso ndikusintha minyewa yolimba yamunthu chifukwa cha kuyanjana kwake ndi biocompatibility, bioactivity and biodegradation.Zakhala zikuyang'aniridwa kwambiri m'munda wa biomedical engineering.α-tricalcium phosphate, β-tricalcium phosphate, amagwiritsidwa ntchito kwambiri muzamankhwala.β Tricalcium mankwala amapangidwa makamaka ndi kashiamu ndi phosphorous, kapangidwe kake ndi ofanana ndi organic zigawo zikuluzikulu za fupa masanjidwewo, ndipo amamanga bwino ku fupa.

Maselo a nyama kapena anthu amatha kukula, kusiyanitsa ndi kuberekana bwinobwino pa zinthu za β-tricalcinum phosphate.Kafukufuku wambiri woyesera amatsimikizira β-tricalcium phosphate, osachita zoyipa, osachita kukanidwa, osachitapo kanthu mwachiwopsezo, palibe chodabwitsa.Chifukwa chake, β Tricalcium phosphate imatha kugwiritsidwa ntchito kwambiri pophatikizana ndi kuphatikizika kwa msana, miyendo, opaleshoni yapakamwa ndi maxillofacial, opaleshoni, ndikudzaza ma cavities a periodontal.

Ntchito ina:

amagwiritsidwa ntchito popanga galasi la opal, ceramic, utoto, mordant, mankhwala, feteleza, zowonjezera zakudya za nyama, mankhwala opangira madzi, stabilizer ya pulasitiki, etc.
