Litšobotsi tse hlano tsa phofo ea alumina ea boleng bo phahameng

1. Ho hanyetsa lik'hemik'hale;
2. Alumina ea bohloeki bo phahameng, lihlahisoa tsa alumina li kholo ho feta 99%;
3. Ho hanyetsa mocheso o phahameng, tšebeliso e tloaelehileng ho 1600 ℃, nako e khutšoanyane ea 1800 ℃;
4. E hanyetsana le serame sa tšohanyetso le mocheso, ha ho bonolo ho phatloha;
5. E amohela grouting mme e na le sekhahla se phahameng.
1. Tšebeliso ea phofo ea alumina ea mofuta oa α

Ka har'a kristale lattice ea mofuta oa α-alumina phofo, li-ion tsa oksijene li tletse haufi-ufi ka li-hexagon, 'me Al3+ e arolelitsoe ka mokhoa o lekanang setsing sa ho hokahanya ha octahedral se pota-potiloeng ke li-ion tsa oksijene.Matla a lattice a maholo haholo, kahoo ntlha ea ho qhibiliha le ntlha e belang e phahame haholo.α-mofuta oxidation Aluminium ha e qhibilihe ka metsing le asiti.E boetse e bitsoa aluminium oxide indastering.Ke thepa ea motheo e tala bakeng sa ho etsa aluminium ea tšepe;e boetse e sebelisetsoa ho etsa litene tse sa tšoaneng tsa refractory, li-crucibles refractory, li-tubes tsa refractory, le lisebelisoa tsa teko ea mocheso o phahameng;e ka boela ea sebelisoa e le li-abrasives le li-flame retardants.Li-agents, li-filler, joalo-joalo;boleng bo phahameng ba mofuta oa α-alumina hape ke thepa e tala bakeng sa tlhahiso ea corundum ea maiketsetso, ruby ​​​​ea maiketsetso le safire;e boetse e sebelisoa bakeng sa tlhahiso ea li-circuits tsa sejoale-joale tse kopaneng tse kholo.

Alumina e kentsoeng e na le matla a ikhethileng a adsorption bakeng sa khase, mouoane oa metsi le mongobo o mong oa metsi.Ka mor'a hore adsorption e phethe, e ka tsosolosoa ka ho futhumatsa hoo e ka bang 175-315 ° C ho tlosa metsi.Adsorption le tsoho li ka etsoa ka makhetlo a mangata.Ntle le ho sebelisoa e le desiccant, e ka boela ea adsorb mouoane oa oli ea lubricating ho tloha oksijene e silafetseng, hydrogen, carbon dioxide, khase ea tlhaho, joalo-joalo E ka boela ea sebelisoa e le catalyst le catalyst carrier le chromatography carrier.

Alumina phofo ke thepa e ka sehloohong e tala bakeng sa tlhahiso ea li-ingots tsa aluminium.E na le litšobotsi tsa ho fofa ha bobebe, metsi a matle, ho qhibiliha habonolo le ho monya ha fluorine ka matla.E loketse ho hlahisa aluminium ea tšepe ka electrolysis e qhibilihisitsoeng ea letsoai.Hape ke thepa ea bohlokoa e tala bakeng sa tlhahiso ea corundum, ceramics le refractories.
