Alumina ke ntho e tloaelehileng eo e seng ea tšepe, e sebelisoang haholo indastering, kaho, lisebelisoa tsa elektroniki, meriana le masimo a mang.

Selelekela sa Alumina

Alumina ke phofo e tšoeu kapa e tšoeu e nang le mokhoa oa molek'hule oa Al2O3 le boima ba molek'hule oa 101.96.Ke motsoako o entsoeng ka aluminium le oksijene, e nang le ntlha e phahameng ea ho qhibiliha le ho thatafala.Alumina ke thepa e tala ea bohlokoa haholo ea indasteri, e sebelisoang haholo ka lirafshoa, likhalase, lisebelisoa tsa elektroniki, meriana le masimo a mang.

Lintho tsa 'mele tsa alumina

Thepa ea 'mele ea alumina haholo-holo e kenyelletsa boima, boima, botsitso ba mocheso, thepa ea optical joalo-joalo.Boima ba alumina ke 3.9-4.0g/cm3, ho thatafala ke Mohs hardness 9, mocheso o tsitsitseng o phahame, 'me ntlha ea ho qhibiliha ke 2054 ℃.Ntle le moo, alumina e boetse e na le thepa e ntle ea optical mme ke thepa ea bohlokoa ea optical.

Lintho tsa lik'hemik'hale tsa alumina

Thepa ea lik'hemik'hale ea alumina haholo-holo e kenyelletsa ts'ebetso ea karabelo ka lintho tse fapaneng tsa lik'hemik'hale, asiti le alkali.Alumina e kopana le asiti ho etsa aluminiamo letsoai le metsi, le alkali ho etsa aluminiamo hydroxide le metsi.Ka nako e ts'oanang, alumina e boetse e na le thepa ea acidic oxides, e ka sebetsanang le lik'hemik'hale tse ngata.

Mokhoa oa ho lokisa oa alumina

Mekhoa e ka sehloohong ea ho lokisetsa alumina ke mokhoa oa lik'hemik'hale, mokhoa oa 'mele joalo-joalo.Mokhoa oa lik'hemik'hale ke haholo-holo ka karabelo ea neutralization ea letsoai la aluminium le hydroxide ho fumana aluminium hydroxide, ebe ka ho chesa mocheso o phahameng ho fumana aluminium oxide.Mokhoa oa 'mele ke haholo-holo ka ho bola ha ore, distillation, crystallization le mehato e meng ea ho fumana alumina.

Sebaka sa kopo ea aluminium

Alumina e sebelisoa haholo indastering, kaho, lisebelisoa tsa elektronike, meriana le masimo a mang.Lefapheng la indasteri, alumina e sebelisoa ha ho etsoa lirafshoa, likhalase, liphahlo joalo-joalo.Lefapheng la kaho, alumina e sebelisoa ho etsa mamati, lifensetere, mabota a likharetene joalo-joalo.Lefapheng la elektronike, alumina e sebelisetsoa ho etsa mapolanka a potoloho, lisebelisoa tsa elektronike, joalo-joalo Lefapheng la meriana, alumina e sebelisoa ha ho etsoa lithethefatsi, lisebelisoa tsa bongaka joalo-joalo.

Tebello ea nts'etsopele ea alumina

Ka nts'etsopele e tsoelang pele ea mahlale le thekenoloji, sebaka sa ts'ebeliso ea alumina se pharalletse le ho feta.Nakong e tlang, ka tsoelo-pele e potlakileng ea lisebelisoa tse ncha, matla a macha le masimo a mang, tlhokahalo ea alumina e tla tsoela pele ho eketseha.Ka nako e ts'oanang, ka ntlafatso e tsoelang pele ea litlhoko tsa ts'ireletso ea tikoloho, theknoloji ea tlhahiso ea alumina e tla tsoela pele ho ntlafala, 'me mekhoa e mengata ea tlhahiso ea tikoloho, e sebetsang hantle le ea ho boloka matla e tla fetoha mokhoa oa tsoelo-pele.

Alumina ke thepa ea bohlokoa eo e seng ea tšepe, e nang le mefuta e mengata ea tšebeliso le boleng ba bohlokoa ba moruo.Nakong e tlang, ka tsoelo-pele e potlakileng ea lisebelisoa tse ncha le matla a macha le masimo a mang, tlhokahalo ea alumina e tla tsoela pele ho eketseha, ha theknoloji ea tlhahiso ea alumina e ntse e tsoela pele ho ntlafala, le ho fana ka menehelo e kholo ho nts'etsopele ea batho.
