Kutholakale ukuthi i-Alumina ikhona okungenani izinhlobo ezingu-8, ziyi-α-Al2O3, θ-Al2O3, γ-Al2O3, δ-Al2O3, η-Al2O3, χ-Al2O3, κ-Al2O3 kanye ne-ρ-Al2O3, izakhiwo zazo zesakhiwo se-macroscopic nazo zihlukile. I-Gamma activated alumina iyikristalu ehlanganisiwe ecishe ibe yi-cubic, enganyibiliki emanzini, kodwa encibilikayo ku-asidi kanye ne-alkali. I-Gamma activated alumina iyisisekeli esibuthakathaka se-asidi, inephuzu lokuncibilika eliphezulu elingu-2050 ℃, ijeli ye-alumina ngesimo se-hydrate ingenziwa ibe yi-oxide ene-porosity ephezulu kanye nobuso obuthile obuphezulu, inezigaba zokuguquka ebangeni lokushisa elibanzi. Ekushiseni okuphezulu, ngenxa yokuphelelwa amanzi emzimbeni kanye ne-dehydroxylation, ubuso be-Al2O3 bubonakala buhambisana ne-oxygen engagcwalisiwe (isikhungo se-alkali) kanye ne-aluminium (isikhungo se-asidi), nomsebenzi we-catalytic. Ngakho-ke, i-alumina ingasetshenziswa njengomthwali, i-catalyst kanye ne-cocatalyst.I-alumina esebenzayo ye-Gamma ingaba yi-powder, ama-granule, ama-strips noma ezinye. Singenza njengoba ufuna. I-γ-Al2O3, ebizwa ngokuthi "i-alumina esebenzayo", uhlobo lwezinto eziqinile ezisakazeka kalula, ngenxa yesakhiwo sayo se-pore esilungisekayo, indawo enkulu ethile, ukusebenza okuhle kokumuncwa, ubuso obunezinzuzo ze-acidity kanye nokuqina okuhle kokushisa, ubuso obune-microporous obunezakhiwo ezidingekayo zesenzo se-catalytic, ngakho-ke iba yi-catalyst esetshenziswa kakhulu, i-catalyst carrier kanye ne-chromatography carrier embonini yamakhemikhali namafutha, futhi idlala indima ebalulekile ekuqhekekeni kwamafutha, ekuhlanzeni i-hydrogenation, ekuguqulweni kwe-hydrogenation, ekuphenduleni kwe-dehydrogenation kanye nenqubo yokuhlanza ukukhishwa kwemoto. I-Gamma-Al2O3 isetshenziswa kabanzi njenge-catalyst carrier ngenxa yokulungiswa kwesakhiwo sayo se-pore kanye ne-acidity ebusweni. Uma i-γ-Al2O3 isetshenziswa njenge-catalyst carrier, ngaphezu kwalokho ingaba nemiphumela yokusabalalisa nokuzinzisa izingxenye ezisebenzayo, inganikeza futhi isikhungo esisebenzayo se-acid alkali, ukusabela okuhambisanayo nezingxenye ezisebenzayo ze-catalytic. Isakhiwo sembobo kanye nezakhiwo zobuso be-catalyst zincike ku-catalyst ye-γ-Al2O3, ngakho-ke i-catalyst esebenza kahle kakhulu ingatholakala ukuze kutholakale ukusabela okuthile kwe-catalytic ngokulawula izakhiwo ze-catalyst ye-gamma alumina.I-alumina esebenzayo ye-gamma ngokuvamile yenziwa nge-pseudo-boehmite yayo yangaphambili ngokusebenzisa ukuphelelwa amanzi emzimbeni okuphezulu okungu-400 ~ 600℃, ngakho-ke izakhiwo ze-physicochemical ebusweni zinqunywa kakhulu yi-pseudo-boehmite yayo yangaphambili, kodwa kunezindlela eziningi zokwenza i-pseudo-boehmite, futhi imithombo ehlukene ye-pseudo-boehmite iholela ekuhlukeni kwe-gamma - Al2O3. Kodwa-ke, kulawo ma-catalyst anezidingo ezikhethekile kumthwali we-alumina, kunzima ukufeza kuphela ukulawula i-pseudo-boehmite yangaphambili, okumele kuthathwe ekulungiseleleni i-prophase kanye nokucubungula ngemuva kokuhlanganisa izindlela zokulungisa izakhiwo ze-alumina ukuze kuhlangatshezwane nezidingo ezahlukene. Lapho izinga lokushisa liphakeme kune-1000 ℃ ekusetshenzisweni, i-alumina iyenzeka ngemuva kokuguqulwa kwesigaba: γ→δ→θ→α-Al2O3, phakathi kwazo γ、δ、θ ziyi-cubic close packing, umehluko ukhona kuphela ekusatshalalisweni kwama-ion e-aluminium ku-tetrahedral kanye ne-octahedral, ngakho-ke lokhu kuguqulwa kwesigaba akubangeli ukushintshashintsha okukhulu kwezakhiwo. Ama-ion e-oxygen esigabeni se-alpha asondelene kakhulu, izinhlayiya ze-aluminium oxide zihlangana kabusha kakhulu, indawo ethile yobuso yehle kakhulu.
