Nanometer alumina powder, eo hape e tsejoang e le nano-alumina, ke sesebelisoa se tsoetseng pele se ntseng se fetola lefapha la mahlale a thepa. Ka thepa ea eona e ikhethang le mefuta e mengata ea ts'ebeliso, ntho ena e nyane empa e le matla e na le tšusumetso e kholo liindastering tse fapaneng.
E 'ngoe ea litšoaneleho tsa bohlokoa tsa nanometer alumina phofo ke boholo ba eona bo nyane ka mokhoa o makatsang, hangata bo maemong a 1-100 nanometers. Saese ena ea ultrafine e e fa sebaka se phahameng le ts'ebetso e ikhethang, e e etsa sebaka se loketseng lits'ebetso tse ngata tse tsoetseng pele.
Lefapheng la li-ceramics, nanometer alumina phofo e sebelisetsoa ho ntlafatsa thepa ea mochine le ea mocheso. Ka ho kenyelletsa nano-alumina ho matrices a ceramic, likarolo tse hlahisoang li bonts'a matla a ntlafetseng, ho tiea le ho hanyetsa ho apara. Sena se lebisitse ho nts'etsopele ea lisebelisoa tsa ceramic tse sebetsang hantle haholo bakeng sa ts'ebeliso ea lits'ebetso tse batloang ke indasteri le boenjiniere.
Ho feta moo, nanometer alumina phofo e boetse e sebelisoa ho hlahisa li-catalysts tse tsoetseng pele. Sebaka sa eona se phahameng le ts'ebetso ea ts'ebetso e etsa hore e be sesebelisoa se setle sa ts'ehetso bakeng sa litsamaiso tsa catalytic, tse nolofalletsang ts'ebetso e ntlafetseng le katleho lits'ebetsong tsa lik'hemik'hale tse kang hydrogenation, oxidation le hydrocracking.
Sebakeng sa lisebelisoa tsa elektronike le li-optoelectronics, nano-alumina e bapala karolo ea bohlokoa ho etsoa ha lisebelisoa tse phahameng tsa ts'ireletso le li-substrates. Thepa ea eona e ikhethang ea dielectric le botsitso ba mocheso li etsa hore e be karolo ea bohlokoa tlhahisong ea lisebelisoa tsa elektroniki, li-capacitor le li-circuits tse kopaneng.
Ho feta moo, tšimo ea biomedical e boetse e ruile molemo mefuteng e ikhethang ea nanometer alumina phofo. E sebelisoa ho nts'etsopele ea lisebelisoa tsa bioactive, litsamaiso tsa phepelo ea lithethefatsi, le scaffolds tsa boenjiniere ba lisele ka lebaka la biocompatibility le bioactivity. Lisebelisoa tsena li na le ts'episo e kholo bakeng sa tsoelo-pele ea phekolo ea meriana le meriana e nchafatsang.
Ho feto-fetoha ha nanometer alumina phofo ho fetela sebakeng sa tokiso ea tikoloho hape. Sebaka sa eona se phahameng le bokhoni ba adsorption bo etsa hore e be thepa e sebetsang bakeng sa ho tlosa litšila le litšila moeeng le metsi, ho kenya letsoho boitekong ba ho boloka tikoloho le taolo ea tšilafalo.
Joalo ka thepa efe kapa efe e tsoetseng pele, tlhahiso le ho ts'oaroa ha nanometer alumina phofo e hloka tlhokomelo e hlokolosi mabapi le polokeho le menahano ea tikoloho. Mehato le liprothokholo tse nepahetseng li tlameha ho lateloa ho netefatsa ts'ebeliso e bolokehileng le ho lahla thepa ena, ho latela mekhoa e metle ea li-nanomaterials.
Qetellong, nanometer alumina powder ke phetoho e fetolang mahlale a thepa, e fana ka mefuta e mengata ea likopo le melemo ho liindasteri tse fapaneng. Thepa ea eona e ikhethang le ts'ebetso e ikhethang e etsa hore e be letlotlo la bohlokoa ho nts'etsopele ea lisebelisoa le mahlale a tsoetseng pele. Ha lipatlisiso le boqapi ba nanotechnology li ntse li tsoela pele ho hatela pele, monyetla oa hore nanometer alumina phofo e tsamaise tsoelo-pele e eketsehileng ho mahlale a thepa e monate e le kannete.
