Kub-kubalumina hmoovyog ua los ntawm kev lag luam aluminium hydroxide thiab bauxite, molecular sieve thiab sib tsoo cov npas raws li cov ntaub ntawv raw, thiab yog calcined hauv qhov tho qhov ntev ntev thaum kub. Thaum cov txheej txheem zom cov pa roj carbon monoxide, cov pa roj carbon nyob hauv cov anthracite txo cov kev ua kom tsis huv xws li silicon oxide (SiO2), hlau oxide thiab titanium oxide hauv alumina rau hauv cov hlau. Cov hlau no sib xyaw ua ke los ua cov ntawv ferroalloy, uas yog tawv dua li ntawm cov sib sib zog ntawm corundum thiab lub dab dej ua kom sov Cov cua sov hauv qab yog sib cais los ntawm corundum yaj.
Kev kub siab alumina hmoov muaj qhov muaj zog tiv thaiv kev tawg, tiv thaiv oxidation, tiv thaiv xeb, thiab muaj cov tshuaj lom neeg ruaj khov. Nws yog abrasive nrog ntau qhov kev siv.
Activated alumina hmoov yog abrasive ua los ntawm kev lag luam aluminium hydroxide hmoov ua cov khoom siv raw, rhuab thiab yaj thiab recrystallized hauv hluav taws xob arc rauv taws. Hauv cov txheej txheem smelting, qhov tsis zoo nyob rau hauv cov ntaub ntawv raw tsis raug tshem tawm. Yog li ntawd, qhov zoo ntawm qhib alumina yog ze ze rau kev coj huv ntawm cov ntaub ntawv raw. Cov ntsiab lus ntawm A12O3 hauv kev ua kom muaj alumina yuav tsum siab dua 99.5%, thiab nws qhov nyuaj yog siab dua qhov ntawm siab-kub alumina hmoov, tab sis nws yog ntau dua nkig.
Nws muaj cov txiav zoo, oxidation thiab roj corrosion tsis kam, thiab muaj zoo rwb thaiv tsev. Nws yog tsuas yog siv rau kev sib tsoo zoo thiab kev sib tsoo zoo ntawm quenched steel thiab alloy hlau, sib tsoo xov thiab zog, thiab lwm yam, lub tshuab ua kom alumina hmoov kuj tseem siv tau rau precision casting thiab qib siab refractory cov ntaub ntawv.
