Hariho ubwoko bubiri bwibikoresho fatizo byo gukora alumina ikora, kimwe ni "ifu yihuta" ikorwa na trialumina cyangwa Bayer ibuye, naho ubundi ikorwa numunyu wa aluminium cyangwa aluminium cyangwa byombi icyarimwe.
X, ρ-alumina n'umusaruro wa X, ρ-alumina
X, ρ-alumina nigikoresho cyingenzi cyo kubyara imipira ya alumina ikora, cyangwa FCA mugihe gito. Mu Bushinwa, byitwa "ifu irekura vuba" kubera ifu ya alumina ikorwa nuburyo bwihuse bwo kubura amazi. "Byihuta depowder" ni uruvange rwa X-alumina na p-alumina hamwe nibintu bitandukanye bitewe nuburyo butandukanye bwo gukora.
X, ρ-alumina yavumbuwe mu 1950 kandi yemejwe na ASTM mu 1960. Mu myaka ya za 70, x n'Uburayi. Urufunguzo rwa tekinoroji ya X, ρ -alumina ni umwuma mwinshi, mubisanzwe mumashanyarazi yigitanda, aho ubushyuhe bwigitanda bugenzurwa na gaze yaka cyangwa amazi. Mu 1975-1980, Ikigo cya Tianjin Institute of Chemical Industry cyateje imbere uburyo bwo guhagarika ubushyuhe bwihuse bwihuse bwibikorwa bya tekinoroji hamwe nibiranga ikoranabuhanga ryubushinwa. Yakoresheje reaction ya cone, yongeramo hydroxide ya aluminiyumu yumye kandi ishenjaguwe, maze ikora imvange ya X-alumina na ρ-alumina ukoresheje flash ikaranze 0.1 ~ 10s mu itanura ryihuta ryihuta.
