Litšobotsi le Ts'ebeliso ea Lisebelisoa tse kholo tsa Alumina

Alumina (letlapa la lik'hemik'hale Al₂O₃) ke ntho ea bohlokoa eo e seng{0}}masebetsi a tšepe a nang le litšobotsi tse ntle tsa 'mele le tsa lik'hemik'hale. E sebelisoa haholo indastering, lisebelisoa tsa elektroniki, tsa bongaka le mafapheng a mang. Mefuta ea eona ea mantlha e kenyelletsa -alumina le -alumina, le mefuta e fapaneng ea kristale ea alumina e bonts'a phapang e kholo ea thepa le ts'ebeliso.

Mefuta e ka Sehloohong ea Lisebelisoa tsa Alumina

1. -Alumina (Corundum)

-Alumina ke mofuta o tsitsitseng oa kristale oa alumina 'me ke karolo ea mantlha ea corundum ea tlhaho (joalo ka ruby ​​​​le safire). E na le sebopeho se teteaneng sa kristale, boima bo phahameng (Mohs hardness 9), sebaka se qhibilihang se fihlang ho 2050 degree, le botsitso bo matla ba lik'hemik'hale le ho hanyetsa ho hotle ho hoholo. Ka lebaka la thepa ena, -alumina e sebelisoa haholo-lisebelisuoa tse sa tsitsang, lithulusi tsa ho seha ka ceramic,{7}}lisebelisoa tse thibelang mocheso o phahameng, le li-bearings tse nepahetseng.

2. -Alumina

-Alumina e na le masoba, -ka holim'a-aluminium oxide e ngata e hlahisoang ke calcining aluminium hydroxide. Sebopeho sa eona se batlang se hlephile sa kristale se fana ka papatso e ntle haholo le ts'ebetso ea matla, se etsa hore e sebelisoe hangata ho li-catalyst supports, li-gas adsorbents, le li-separators tsa lithium battery{4}}Alumina e boetse e na le ts'ebeliso ea bohlokoa lirapeng tsa letsopa, lisebelisoa tsa ho bentša le likarolo tse ling.

Lisebelisoa tse ka Sehloohong tsa Alumina

1. Li-Ceramics tsa indasteri

Lirafshoa tsa aluminium, ka lebaka la matla a tsona a phahameng, ho thatafala ha tsona, le{0}}tse hanyetsanang le mocheso o phahameng, li sebelisoa haholo ha ho etsoa liqibi,{1}}li lilara tse sa tsitsang, le li-electronic substrates. -Alumina ceramics li bonts'a botsitso bo ikhethang, haholo-holo{3}litikolohong tsa mocheso o phahameng, ho li etsa hore li tšoanelehe bakeng sa indasteri ea boemo bo holimo{4}

2. Electronics le Semiconductors

High-alumina e hloekileng (ka holimo ho 99.9%) ke sesebelisoa sa bohlokoa bakeng sa ho etsoa ha litšepe tse kopantsoeng tsa potoloho, lirafshoa tsa ceramic, le lisebelisoa tsa ho paka tsa LED. Insulation ea eona e ntle haholo le conductivity ea mocheso e etsa hore e be thepa ea bohlokoa haholo indastering ea lisebelisoa tsa elektroniki.

3. Bongaka le Mabenyane

Ho thatafala ha Alumina ho etsa hore e be sesebediswa se loketseng manonyeletso a maiketsetso le ho kenngwa meno, ha dirubi le safire (likristale tsa tlhaho tsa alumina) li sebelisoa{0}}mabenyaneng a phahameng bakeng sa botle le ho tšoarella ha tsona.

Qetello

Alumina, thepa e feto-fetohang, e bapala karolo ea bohlokoa mafapheng a fapaneng, ho kenyeletsoa indasteri, lisebelisoa tsa elektroniki le tsa bongaka, ka lebaka la mefuta ea eona e fapaneng ea kristale. Ka tsoelopele ho mahlale a thepa, boholo ba lisebelisoa tsa alumina li tla tsoela pele ho hola, haholo-holo mafapheng a matla a macha, tšireletso ea tikoloho, le{1}}mahlale a phahameng a tlhahiso ea theknoloji, moo bohlokoa ba ona bo tla bonahala le ho feta.
