Kune marudzi maviri ezvigadzirwa zvekugadzira aluminium activated, imwe i "fast powder" inogadzirwa ne trialumina kana Bayer stone, uye imwe inogadzirwa nealuminium kana aluminium munyu kana zvose panguva imwe chete.
X, ρ-alumina uye kugadzirwa kweX,ρ-alumina
X, ρ-alumina ndiyo huru mbishi yekugadzirwa kwemabhora akaiswa alumina, kana FCA kwenguva pfupi. MuChina, inonzi "fast release poda" nekuda kwealumina powder inogadzirwa nekukurumidza kupera mvura mumuviri."Fast depowder" isanganiswa yeX-alumina uye p-alumina ine zvakasiyana-siyana nekuda kwemamiriro akasiyana ekugadzira.
X,ρ-alumina yakawanikwa muna 1950 uye yakasimbiswa neASTM muna 1960. Mumakore ekuma1970, x neEurope. Kiyi yeX, ρ -alumina tekinoroji inokurumidza kupera mvura mumuviri, kazhinji mumubhedha unoyerera, uko tembiricha yemubhedha inodzorwa negasi rinopisa kana mvura. Muna 1975-1980, Tianjin Institute of Chemical Indasitiri yakabudirira kugadzira tekinoroji yekudziisa nekukurumidza kubvisa tekinoroji yekugadzira ine hunhu hweChinese tekinoroji. Yakashandisa cone reactor, yakawedzera yakaoma uye yakapwanyika aluminium hydroxide, uye yakagadzira musanganiswa weX-alumina uye ρ-alumina neflash kugocha 0.1 ~ 10s muchoto chekukurumidza kupera mvura.
