I-Nanometer alumina powder, eyaziwa nangokuthi i-nano-alumina, iyinto esezingeni eliphezulu ebilokhu iguqula umkhakha wesayensi yezinto zokwakha. Ngezakhiwo zayo eziyingqayizivele kanye nohlu olubanzi lwezinhlelo zokusebenza, le nto encane kodwa enamandla yenza umthelela omkhulu ezimbonini ezihlukahlukene.
Esinye sezici ezibalulekile ze-nanometer alumina powder usayizi wayo wezinhlayiyana ezincane ngendlela emangalisayo, ngokuvamile ebangeni lama-nanometer angu-1-100. Lo sayizi we-ultrafine uyinikeza indawo ephezulu kanye nokusebenza kabusha okukhethekile, okuyenza ibe ikhandidethi efanelekile yezinhlelo zokusebenza eziningi ezithuthukile.
Emkhakheni we-ceramics, i-nanometer alumina powder isetshenziselwa ukuthuthukisa izakhiwo zemishini nezokushisa zezinto. Ngokuhlanganisa i-nano-alumina kumatrices e-ceramic, izinhlanganisela eziwumphumela zibonisa amandla athuthukisiwe, ukuqina, nokumelana nokuguga. Lokhu kuye kwaholela ekuthuthukisweni kwezingxenye ze-ceramic ezisebenza kahle kakhulu ezizosetshenziswa ekufuneni izicelo zezimboni nezobunjiniyela.
Ngaphezu kwalokho, i-nanometer alumina powder iphinde isetshenziswe ekukhiqizeni ama-catalysts athuthukile. Indawo yayo ephezulu nokusebenza kabusha kuyenza ibe into enhle kakhulu yokweseka yezinhlelo ze-catalytic, okuvumela ukusebenza okuthuthukisiwe nokusebenza kahle ezinqubweni zamakhemikhali ezifana ne-hydrogenation, oxidation, kanye ne-hydrocracking.
Emkhakheni we-electronics kanye ne-optoelectronics, i-nano-alumina idlala indima ebalulekile ekwakhiweni kwezinto ezivikelayo ezisebenza kahle kakhulu nama-substrates. Izakhiwo zayo eziyingqayizivele ze-dielectric kanye nokuzinza kokushisa kuyenza ibe yingxenye ebalulekile ekukhiqizeni izinto zikagesi, ama-capacitor, namasekethe ahlanganisiwe.
Ngaphezu kwalokho, inkambu ye-biomedical nayo izuze ezintweni eziyingqayizivele ze-nanometer alumina powder. Isetshenziswa ekuthuthukisweni kwezinto ezisebenzayo, amasistimu okulethwa kwezidakamizwa, nezikafula zobunjiniyela bezicubu ngenxa yokuhambisana kwayo ne-bioactivity. Lezi zicelo zinesithembiso esihle sokuthuthuka kwezokwelapha kanye nemithi yokuvuselela.
Ukuguquguquka kwe-nanometer alumina powder kudlulela endaweni yokulungisa imvelo futhi. Indawo yayo ephezulu kanye namandla okukhangisa kuyenza ibe into esebenzayo yokususa izinto ezingcolisayo kanye nokungcola emoyeni nasemanzini, okunikela emizamweni yokusimama kwemvelo nokulawula ukungcola.
Njenganoma iyiphi impahla ethuthukisiwe, ukukhiqizwa kanye nokuphathwa kwe-nanometer alumina powder kudinga ukunakwa ngokucophelela kokuphepha kanye nokucatshangelwa kwemvelo. Izinyathelo zokuphepha ezifanele kanye nezinqubo kufanele zilandelwe ukuze kuqinisekiswe ukusetshenziswa okuphephile nokulahlwa kwalokhu kwaziswa, ngokuhambisana nezinqubo ezingcono kakhulu zama-nanomaterials.
Sengiphetha, i-nanometer alumina powder ishintsha umdlalo kusayensi yezinto zokwakha, enikeza uxhaxha olubanzi lwezinhlelo zokusebenza nezinzuzo kuzo zonke izimboni ezahlukahlukene. Izakhiwo zayo eziyingqayizivele nokusebenza okukhethekile kuyenza ibe yimpahla ebalulekile ekuthuthukisweni kwezinto ezithuthukisiwe nobuchwepheshe. Njengoba ucwaningo nokuqanjwa okusha kwe-nanotechnology kuqhubeka, amandla e-nanometer alumina powder ukuze aqhubekisele phambili intuthuko kwezesayensi yezinto ezibonakalayo ayajabulisa ngempela.
