Khatelo-peleng ea bohlokoa lefapheng la mahlale a lintho tse bonahalang, bafuputsi ba hatetse pele ho hlahiseng bohloeki bo phahameng α-Al2O3 (alpha-alumina), thepa e tsejoang ka thepa ea eona e ikhethang le lits'ebetso tse fapaneng. Sena se tla ka mor'a lipolelo tsa pejana tsa Amrute et al. tlalehong ea bona ea 2019, e boletseng hore ha ho mekhoa e teng e ka hlahisang α-Al2O3 e nang le bohloeki bo phahameng le libaka tse holimo tse fetang menyako e itseng. Liphuputso tsa bona li hlahisitse matšoenyeho mabapi le mefokolo ea mekhoa ea hona joale ea tlhahiso le litlamorao ho liindasteri tse itšetlehileng ka thepa ena ea bohlokoa.
Alpha-alumina ke mofuta oa aluminium oxide o nkoang e le oa bohlokoa haholo bakeng sa ho thatafala ha oona, botsitso ba mocheso, le thepa ea ho kenya motlakase. E sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyeletsoa li-ceramics, li-abrasives, le joalo ka substrate ea lisebelisoa tsa elektroniki. Tlhokahalo ea bohloeki bo phahameng ba α-Al2O3 e ntse e eketseha, haholo-holo masimong a lisebelisoa tsa elektronike le li-ceramics tse tsoetseng pele, moo litšila li ka amang ts'ebetso le ts'epo haholo.
Tlaleho ea 2019 ea Amrute et al. e totobalitse liqholotso tseo bafuputsi le bahlahisi ba tobaneng le tsona ho fihlela maemo a lakatsehang a bohloeki le litšobotsi tsa sebaka se ka holimo. Ba hlokometse hore mekhoa ea setso, joalo ka lits'ebetso tsa sol-gel le synthesis ea hydrothermal, hangata e ne e fella ka lisebelisoa tse haelloang ke litekanyetso tse phahameng tse hlokahalang bakeng sa lits'ebetso tsa morao-rao. Khaello ena e ile ea baka tšitiso ho boqapi le nts'etsopele liindastering tse 'maloa tsa theknoloji e phahameng.
Leha ho le joalo, tsoelo-pele ea morao tjena e qalile ho rarolla mathata ana. Boiteko ba ho etsa lipatlisiso bo kopanetsoeng bo amang bo-rasaense ba tsoang mekhatlong e 'maloa e etelletseng pele bo lebisitse ho nts'etsopele ea mokhoa o mocha oa ho kopanya o kopanyang mekhoa e tsoetseng pele ea ho hlahisa bohloeki bo phahameng ba α-Al2O3 e nang le libaka tse ntlafalitsoeng haholo. Mokhoa ona o mocha o sebelisa motsoako oa motsoako oa microwave-assisted synthesis le mekhoa e laoloang ea ho bala, e lumellang hore ho be le taolo e ntle holim'a thepa ea thepa.
Bafuputsi ba tlalehile hore mokhoa oa bona ha oa ka oa finyella maemo a phahameng a bohloeki feela empa hape o ile oa fella ka α-Al2O3 e nang le libaka tse holim'a metsi tse fetang tse tlalehiloeng pele libukeng. Katleho ena e na le monyetla oa ho bula mekhoa e mecha ea ts'ebeliso ea α-Al2O3 lits'ebetsong tse fapaneng, haholo lefapheng la lisebelisoa tsa elektroniki, moo tlhoko ea lisebelisoa tse sebetsang hantle e ntseng e eketseha.
Ntle le ts'ebeliso ea eona ho lisebelisoa tsa elektronike, α-Al2O3 ea boleng bo phahameng e boetse e bohlokoa tlhahisong ea li-ceramics tse tsoetseng pele, tse sebelisoang liindastering tse sa tšoaneng, ho akarelletsa le sefofane, likoloi, le biomedical. Bokhoni ba ho hlahisa α-Al2O3 e nang le thepa e ntlafalitsoeng e ka lebisa ho nts'etsopele ea lisebelisoa tse ncha tse bobebe, tse matla, tse sa khoneng ho roala le ho bola.
Liphello tsa lipatlisiso tsena li fetela ka ntle ho tlhahiso ea thepa feela. Bokhoni ba ho theha bohloeki bo phahameng ba α-Al2O3 e nang le libaka tse ntlafalitsoeng tsa bokaholimo bo ka boela ba lebisa tsoelopeleng ea catalysis le ts'ebeliso ea tikoloho. Mohlala, α-Al2O3 hangata e sebelisoa e le ts'ehetso ea ts'ehetso ea karabelo ea lik'hemik'hale, 'me ho ntlafatsa thepa ea eona ho ka ntlafatsa ts'ebetso le katleho ea lits'ebetso tse fapaneng tsa matla.
Ho feta moo, mokhoa o mocha oa ho kopanya o ka bula tsela bakeng sa lipatlisiso tse tsoelang pele ka mekhahlelo e meng ea aluminium oxide le lisebelisoa tsa bona tse ka bang teng. Ha bafuputsi ba ntse ba tsoela pele ho hlahloba thepa le boitšoaro ba lisebelisoa tsena, ho na le thahasello e ntseng e eketseha tšebelisong ea tsona ea ho boloka matla, ho lokisoa ha tikoloho, esita le ho nts'etsopele ea libeteri tsa moloko o latelang.
Liphuputso tse tsoang phuputsong ena ea morao-rao li phatlalalitsoe koranteng ea saense ea lisebelisoa tse ka sehloohong, moo li hapileng tlhokomelo ho tsoa mekhatlong ea thuto le ea indasteri. Litsebi tsa tšimo li rorisitse mosebetsi ona e le mohato oa bohlokoa oa pele oa ho hlōla mefokolo e khethiloeng ke Amrute et al. 'me ba bontšitse tšepo mabapi le bokamoso ba tlhahiso ea α-Al2O3.
Ha tlhoko ea lisebelisoa tse sebetsang hantle e ntse e hola, bokhoni ba ho hlahisa bohloeki bo phahameng ba α-Al2O3 ka thepa e ntlafalitsoeng bo tla ba bohlokoa. Katleho ena ha e sebetsane feela le liqholotso tse totobalitsoeng liphuputsong tse fetileng empa e boetse e rala motheo oa lintlafatso tse ling tsa mahlale a lintho tse bonahalang. Tšebelisano pakeng tsa bafuputsi le bankakarolo ba indasteri e tla ba ea bohlokoa ho fetoleleng liphuputso tsena hore e be litšebeliso tse sebetsang tse ka tsoelang makala a mangata a fapaneng molemo.
Qetellong, tsoelo-pele ea morao tjena tlhahisong ea boleng bo phahameng ba α-Al2O3 e emela mohato oa bohlokoa ho saense ea lintho tse bonahalang. Ka ho hlōla liphephetso tse bontšitsoeng liphuputsong tsa pejana, bafuputsi ba butse menyetla e mecha ea ho sebelisa boitsebiso bona bo feto-fetohang lits'ebetsong tse fapaneng tsa theknoloji e phahameng. Ha tšimo e ntse e tsoela pele ho fetoha, ho hlakile hore bokamoso ba α-Al2O3 le lihlahisoa tsa eona li na le tšepiso e kholo ea boqapi le nts'etsopele ho pholletsa le liindasteri tse ngata.
