Leben sare oo aluminium ah oo loogu talagalay foornada dhalada
Leben alumina sare foornada dhalada ah
Qaybaha ugu muhiimsan ee lebenka aluminiumka sare waa SiO2 iyo Al2O3, laakiin nuxurka alumina waa inuu ka weyn yahay 46%. Waxay ka samaysan tahay corundum, bauxite ama sillimanite macdanta taxanaha ah (Al2O3-SiO2). Cufnaanta waa 2.3 ~ 3.0g/cm3, porosity-ga muuqda waa qiyaastii 18% ~ 23%, heerkulka isticmaalka ugu badanna waa 1500 ~ 1650℃. Hooska hoose ee lebenka aluminiumka sare, ayaa si fiican u caabbinta daxalka. Darbiga barkada ee qaybta qaboojinta, qulqulka dib-u-kicinta, iyo derbiga dib-u-dhaqaajinta waxaa lagu dhisi karaa leben sare oo aluminium ah.
