Aluminium Carbide phofo, Al4C3

E sebelisoa metallurgy e le tlhahiso ea lihlahisoa le tlhahiso ea methane.
Aluminium carbide hangata e sebelisoa e le sehokela ho ntlafatsa matla a lisebelisoa tse tharo tsa aluminium (al-Si-ALC, al-AlTI-ALC). Ntle le moo, AlC ke motsoako oa bohlokoa lebaleng la theknoloji ea indasteri ea tšepe ea aluminium.

E sebelisoa metallurgy e le tlhahiso ea lihlahisoa le tlhahiso ea methane.
Aluminium carbide e sebelisoa khafetsa e le tlatsetso ho ntlafatsa matla a lisebelisoa tse tharo tsa aluminium (al-Si-ALC, al-AlTI-ALC). Ntle le moo, AlC ke motsoako oa bohlokoa lebaleng la theknoloji ea indasteri ea tšepe ea aluminium. E sebelisetsoa ho fokotsa li-oxide tsa tšepe indastering ea metallurgic, lik'hemik'hale tse sebetsanang le lik'hemik'hale, le lisebelisoa tse tsoetseng pele tsa letsopa tse kang mocheso o phahameng, ho itšeha le hlobo indastering ea ceramic. Joalo ka motsoako oa ionic, liathomo tsa khabone li teng ka mokhoa o arohaneng oa C ka sebopeho sa Alt. C e na le alkalinity e matla mme e hlahisa methane ka C + 4H → CH nakong ea hydrolysis, ka hona AlC le eona ACTS joalo ka jenereithara ea methane le desiccant. Ka nako e ts'oanang, rhombohedron ea
