Bangaren β-TCP yana kama da abun da ke cikin ma'adinai na kashi kuma yana da farin amorphous foda ba tare da wari ba. Barga a cikin iska, bazuwar a cikin ruwan zafi, mai narkewa a cikin tsarma hydrochloric acid da nitric acid, kusan insoluble cikin ruwa, ethanol da acetic acid. Kyakkyawan dacewa da ilimin halitta, lalacewa a ƙarƙashin yanayin ilimin lissafi, sha ta kyallen takarda.
β-tricalcium phosphate (β-TCP) yana da kyau biodegradability, biocompatibility da osteoinductive ikon. Bayan an dasa shi a cikin jikin mutum, gurɓataccen calcium da phosphorus na iya shiga tsarin rayuwa kuma su haifar da sabon kashi, don haka ana amfani da shi sosai. Gyara naman kashi. Duk da haka, taurinsa ba shi da kyau, maras kyau, kuma ƙarfin ɗaukar kaya ba shi da kyau. An kuma yi amfani da Poly L-lactic acid (PLLA) don gyaran nama na ƙashi saboda kyakkyawan yanayin da ya dace da kuma biodegradability.
Tricalcium phosphate yana da kyau bioacompatibility, bioactivity da biodegradaability. Kyakkyawan gyare-gyaren nama mai ƙarfi da kayan maye ga jikin ɗan adam kuma an sa ido sosai a fagen injiniyan halittu. Wani nau'i na musamman na tricalcium phosphate, beta-tricalcium phosphate, ana amfani dashi a magani. Kyakkyawan biocompatibility, bioactivity da biodegradaability. Yana da manufa mai wuyar gyara nama da kayan maye. A matsayin danyen kashin wucin gadi, an yi amfani da shi sosai wajen gyaran kashi, tiyatar robobi da gyaran fuska, tiyatar hakori, gyare-gyare saboda rauni, raunin kashi da hadewar kashi da ciwace-ciwacen daji ke haifarwa, kumburi, cututtukan kashi da sauransu. zuwa abinci a matsayin amintaccen abinci mai gina jiki don haɓaka yawan shan calcium, kuma ana iya amfani dashi don hanawa ko magance alamun ƙarancin calcium. A lokaci guda kuma, ana iya amfani da shi azaman wakili na anti-caking, mai daidaita pH, wakilin buffering, da sauransu a cikin abinci.
β-tricalcium phosphate yawanci ya ƙunshi calcium da phosphorus, kuma abun da ke cikinsa yayi kama da ɓangaren inorganic na matrix na kashi, kuma yana da kyau a hade da kashi. Dabbobi ko ƙwayoyin ɗan adam na iya girma, bambanta da ninka akan kayan β-tricalcium phosphate.
