Kukho iintlobo ezimbini zezinto ezisetyenziswayo zokwenza i-alumina esebenzayo, enye "yi-fast powder" eveliswa yi-triallumina okanye i-Bayer stone, kwaye enye iveliswa yi-aluminate okanye ityuwa ye-aluminium okanye zombini ngaxeshanye.
X,ρ-alumina kunye nokuveliswa kwe-X,ρ-alumina
I-X, i-ρ-alumina yeyona nto iphambili ekuveliseni iibhola ze-alumina ezisebenzayo, okanye i-FCA ngamafutshane. E-China, ibizwa ngokuba yi-"fast release powder" ngenxa ye-alumina powder eveliswa ngendlela yokuphelelwa ngamanzi ngokukhawuleza. "I-Fast depowder" ngumxube we-X-alumina kunye ne-p-alumina kunye nomxholo owahlukileyo ngenxa yeemeko ezahlukeneyo zemveliso.
I-X,ρ-alumina yafunyanwa ngo-1950 yaza yaqinisekiswa yi-ASTM ngo-1960. Ngeminyaka yoo-1970, i-x neYurophu. Isitshixo setekhnoloji ye-X, ρ -alumina kukuphelelwa ngamanzi ngokukhawuleza, ngokuqhelekileyo kwi-reactor yebhedi enyibilikisiweyo, apho ubushushu bebhedi bulawulwa yigesi yokutsha okanye ulwelo. Ngo-1975-1980, iTianjin Institute of Chemical Industry yaphuhlisa ngempumelelo itekhnoloji yokuvelisa i-suspension heating fast stripping eneempawu zobuchwepheshe baseTshayina. Yasebenzisa i-cone reactor, yongeza i-aluminium hydroxide eyomileyo netyumkileyo, yaza yenza umxube we-X-alumina kunye ne-ρ-alumina ngokurhabaxa nge-0.1 ~ 10s kwisithando somlilo esikhawulezayo.
