Leben sare oo aluminium ah ayaa lagu soo saaraa xulashada bauxite chamotte oo ah alaabta ceeriin ee ugu weyn, oo lagu shido 1450-1470 ° C iyadoo la raacayo hannaan horumarsan oo leh koontarool tayo adag leh. Buundooyinka Dabka ee Alumina Sare waxaa lagu soo saaray aluminium ama alaab kale oo ceeriin ah oo ay ku jiraan maaddo aluminium sare ah iyada oo loo marayo qaabaynta iyo toogashada. Sababtoo ah hantideeda dhexdhexaadka ah ee alumina refractory waxay iska caabin kartaa nabaad-guurka aashitada.
Ka dhex xulo oo shaandhee chamotte si aad u nadiifiso ka hor inta aanad jebin, taas oo hagaajin karta tayada lebenka aluminium ee sare. Sababtoo ah waxaa jira saamiga sare ee grog ee maaddooyinka oo gaari kara 90 ~ 95%. Dooro oo baadh deiroing ka hor inta aan la burburin.
Marka loo eego nuxurka kala duwan ee Al2O3, lebenka alumina ee sarreeya waxaa loo kala saari karaa Saddex Fasalo oo Shiinaha ah.
Fasalka 1-aad ee buundooyinka aluminiumka sare ayaa leh wax ka badan 75% Al2O3.
Fasalka 2-aad ee buundooyinka aluminiumka sare leh ayaa ka kooban 60 ~ 75% Al2O3.
Fasalka III Bricks Alumina Sare waxay leeyihiin 48 ~ 60% ka kooban Al2O3.
Lebenka aluminiumka sare wuxuu leeyahay sifooyin aad u wanaagsan sida waxqabadka heerkulka sare, daxalka weyn iyo xirashada iska caabinta, cufnaanta bulk sare, maadada birta oo yar, iwm.

Leben aluminium sare ah ayaa loo isticmaali karaa foornada qaraxa, shooladda qaraxa kulul, foornada koronto. sidoo kale lebenka dabka aluminium sare loo isticmaalo beeraha birta iyo birta, nonferrous, galaas, sibidhka, ceramics, petrochemical, mashiinka, kuleyliyaha, warshadaha iftiinka, korontada, iyo warshadaha military iwm.
