Kunezinhlobo ezimbili zezinto ezingavuthiwe zokukhiqiza i-alumina ecushiwe, enye “impushana esheshayo” ekhiqizwa itshe le-tricumina noma i-Bayer, kanti enye ikhiqizwa usawoti we-alumina noma i-aluminium noma kokubili ngesikhathi esisodwa.
I-X, i-ρ-alumina kanye nokukhiqizwa kwe-X, ρ-alumina
I-X, i-ρ-alumina iyimpahla eyinhloko yokukhiqiza amabhola e-alumina acushiwe, noma i-FCA ngamafuphi. E-China, ibizwa ngokuthi “impushana ekhishwa ngokushesha” ngenxa yempushana ye-alumina ekhiqizwa indlela yokuphelelwa amanzi emzimbeni ngokushesha.”I-Depowder esheshayo” iyingxube ye-X-alumina ne-p-alumina enokuqukethwe okuhlukene ngenxa yezimo ezihlukene zokukhiqiza.
I-X,ρ-alumina yatholwa ngo-1950 futhi yaqinisekiswa yi-ASTM ngo-1960. Ngeminyaka yo-1970, x naseYurophu. Isihluthulelo se-X, ρ -alumina ubuchwepheshe ukuphelelwa amanzi emzimbeni ngokushesha, ngokuvamile ku-reactor yombhede omanzi, lapho izinga lokushisa lombhede lilawulwa igesi elivuthayo noma uketshezi. Ngo-1975-1980, i-Tianjin Institute of Chemical Industry yathuthukisa ngempumelelo ubuchwepheshe bokukhiqiza bokufudumeza obunqamula ngokushesha obunezici zobuchwepheshe baseShayina. Isebenzise i-cone reactor, yengeza i-aluminium hydroxide eyomile nechoboziwe, futhi yenza ingxube ye-X-alumina ne-ρ-alumina ngokugazinga nge-flash 0.1~10s esithandweni sokuphelelwa amanzi ngokushesha.
