Ka kakaretso, litene tse phahameng tsa aluminium ha lia lokela ho sebelisoa seboping sa sepakapaka sa alkaline.Hobane alkaline le acidic medium e boetse e na le chlorine, e tla phunyeletsa likarolo tse tebileng tsa litene tse phahameng tsa alumina ka mokhoa oa gradient, e leng se tla etsa hore setene sa refractory se oe.
Setene se phahameng sa aluminium ka mor'a khoholeho ea sepakapaka sa alkaline ke mapetsong a rapameng.Khoholeho ea mobu e entsoe ka mafura a bohlooho, likhase tse tukang, le likaroloana tsa alkaline lihlahisoa tse ling.Likarolo tsena li sebetsana le mohato oa khalase le lejoe la mullite seteneng se phahameng sa aluminium.
Litene tse phahameng tsa aluminium tse nang le alkaline e senyehileng li tla hlaha holimo.Ho chesa lik'hemik'hale tsa khase ho tla boela ho hlahise nitrate e khahlehang, sedimentation ka lekhalo la litene tse phahameng tsa aluminium;karabelo ea maqhoqhoane a hlahisitsoeng e tla theha mohato o mocha o rarahaneng.Ha li-nitrile tsa lehlohonolo tse se nang metsi li kopana le vagram e hlahisitsoeng, karabelo ea anti -vaporization e tla etsahala, e leng se etsang hore setene se phahameng sa aluminium se honye kapa se theohe.Ho feta moo, kutu ea mocheso e boetse e tebile haholo bakeng sa kutu ea litene tse refractory.Ka lebaka la khoholeho ea Fang quartz, Skywine, le quartz crystal silica.Tšebeliso ea lithaelese tsa mollo e tla ba tse tebileng ho feta li-noodle tse batang.
Tšenyo ea litene tsa silicon dioxide le eona e tebile haholo.Silika e qhibiliha ka setene se phahameng sa aluminium - mokelikeli oa metsi.Nitrate ea lehlohonolo e qhibilihang le majoe a silicon a tlaase a qhibiliha a etsa karolo e kholo ea mokelikeli.Ho phahama ha silika ka har'a setene, ho na le palo e kholo ea karolo ea mokelikeli.Mekhahlelo ea metsi e feteletseng e tla holofatsa litene tse phahameng tsa aluminium.Silicon silicon e boetse e senyehile ho litene.Hobane silika ea mahala e jeoa, karolo ea Mo Lai Shi e tla senyeha.Ka mor'a karabelo ea lickle nitrate le lejoe la mullite li ka baka katoloso e senyang ea setene se phahameng sa aluminium.
Litene tse phahameng tsa aluminium li na le khanyetso e babatsehang ea mocheso o phahameng le abrasion.Li sebelisoa haholo ka har'a lesela la libopi tse fapaneng tsa indasteri, joalo ka libono tse phatlohang, lionto tsa moea o chesang, le libono tsa rotary.Leha ho le joalo, sebakeng sa sebōpi sa indasteri ea alkaline, tšebeliso ea litene tse phahameng tsa alumina e lekanyelitsoe.
Lintho tsa lik'hemik'hale tsa litene tse phahameng tsa alumina li etsa hore li hanyetse liphello tsa libaka tse nang le asiti.Leha ho le joalo, sebakeng se nang le alkaline e ngata haholo, e kang libōpi tsa samente kapa libōpi tsa khalase, litene tse phahameng tsa aluminium li tla itšoara ka li-oxide tsa tšepe tsa alkali, tse etsang hore litene li phunye le ho senyeha.Karabelo pakeng tsa litene tsa Al2O3 le li-oxide tsa tšepe tsa alkali hangata li etsa hore ho thehoe gel ea alkali aluminosilicate, e nang le sebaka se tlaase sa ho qhibiliha 'me se ka phalla habonolo har'a mapetsong.
Ho rarolla bothata bona, ho sebelisitsoe maqheka a 'maloa ho ntlafatsa ho hanyetsa ha litene tse phahameng tsa aluminium libakeng tsa alkaline.Tharollo e 'ngoe ke ho eketsa magnesia kapa spinel ho litene tse phahameng tsa alumina.Magnesia kapa spinel e tla itšoara ka li-oxide tsa tšepe tsa alkali ho theha mekhahlelo e tsitsitseng ea spinel, e ka ntlafatsang ho hanyetsa ha litene tsa Al2O3 ho senya ho bakoang ke ho itšoara ka alkali.Tharollo e 'ngoe ke ho sebelisa tšireletso e sireletsang holim'a litene tse phahameng tsa alumina ho thibela ho kopana ka ho toba le tikoloho ea alkaline.
Ka kakaretso, litene tse phahameng tsa aluminium li na le ts'ebetso e fokolang sebakeng sa sebōpi sa sebōpi sa alkaline.Ho matlafatsa khanyetso ea litene tsa Al2O3 libakeng tsa alkaline, hoa hlokahala ho eketsa liminerale tse itseng kapa liphahlo ho qoba liketso tse kotsi ka li-oxide tsa tšepe tsa alkali.Ho bohlokoa ho khetha thepa e nepahetseng bakeng sa lesela la sebōpi sa indasteri ho fokotsa likotsi tse ka bang teng le ho boloka litšenyehelo.
