Ceramic ntchito calcium phosphate

mfundo

Tricalcium phosphate ili ndi biocompatibility yabwino, bioactivity ndi biodegradability. Ndi chinthu choyenera kukonzanso minofu yamunthu yolimba ndikuyisintha, ndipo yakhala ikuyang'aniridwa kwambiri pankhani ya uinjiniya wa biomedical ndi makampani a ceramic.

ntchito:

Kugwiritsa ntchito: Pogwiritsira ntchito mankhwala a ceramic, monga ceramic bone China tableware ndi mbiya zadothi ndi mbale zadothi, ndi zina.... Osagwiritsa ntchito mankhwala kapena ntchito zina.

Kukonza kashiamu mankwala ceramic ufa makamaka zikuphatikizapo yonyowa njira ndi olimba anachita njira. Njira zonyowa zimaphatikizapo: njira ya hydrothermal reaction, njira yamadzimadzi yamadzimadzi, njira ya sol-gel, kuwonjezera, njira ya organic precursor matenthedwe, njira ya microemulsion medium synthesis, etc. ndi kukula kwa tinthu tating'ono.

Olimba boma anachita njira (anachita popanda mpweya) zambiri amapereka mankhwala ndi stoichiometry ndi wathunthu crystallization, koma amafuna ndi kutentha ndi kutentha nthawi mankhwala, ndi sinterability wa ufa ndi osauka.

Calcium phosphate ceramic zida zopezedwa ndi njira ya hydrothermal nthawi zambiri zimakhala ndi crystallinity yayikulu ndipo Ca / P pafupi ndi mtengo wa stoichiometric.

Ubwino wa njira yothetsera mpweya ndi njira yosavuta komanso yodalirika, kuyera kwakukulu kwa gulu, koyenera kupanga zoyesera kuposa njira zina, ndi nano-kakulidwe CHIKWANGWANI tinthu ufa akhoza kukonzekera pansi pa chikhalidwe kuti kutentha si upambana 100 ℃. Kupaka kwa Hydroxyapatite kumatha kukonzedwanso ndi njira yothetsera mpweya.

Sol gel osakaniza njira angagwiritsidwe ntchito pokonzekera amorphous, nano-kakulidwe kashiamu mankwala ceramic ufa ndi Ca / P chiŵerengero pafupi stoichiometric mtengo. Ubwino wa sol gel osakaniza njira ndi mkulu chiyero, superfine, mkulu kufanana, controllable tinthu mawonekedwe ndi kukula, anachita pa firiji ndi zipangizo zosavuta; The kuipa ndi ndondomeko mankhwala zovuta, miyeso ayenera kumwedwa kupewa agglomeration ndi kuipitsidwa kwa chilengedwe chifukwa cha zosungunulira madzi.

Njira yothetsera mpweya ndi njira ya sol gel ndi njira zokonzekera za calcium phosphate ceramic powder
