Kufunyenwe ukuba i-Alumina ikhona ubuncinane kwiifom ezisi-8, ziyi-α-Al2O3, θ-Al2O3, γ-Al2O3, δ-Al2O3, η-Al2O3, χ-Al2O3, κ-Al2O3 kunye ne-ρ-Al2O3, iipropati zazo zesakhiwo se-macroscopic nazo zahlukile. I-Gamma activated alumina yikristale evaliweyo ye-cubic, enganyibilikiyo emanzini, kodwa inyibilikayo kwi-asidi kunye ne-alkali. I-Gamma activated alumina yinkxaso ye-asidi ebuthathaka, ine-high melting point 2050 ℃, ijeli ye-alumina kwimo ye-hydrate ingenziwa ibe yi-oxide ene-porosity ephezulu kunye nomphezulu othile ophezulu, inezigaba zotshintsho kuluhlu olubanzi lobushushu. Kubushushu obuphezulu, ngenxa yokuphelelwa ngamanzi emzimbeni kunye ne-dehydroxylation, ubuso be-Al2O3 bubonakala buhambelana ne-oxygen engagcwaliyo (iziko le-alkali) kunye ne-aluminium (iziko le-asidi), kunye nomsebenzi we-catalytic. Ke ngoko, i-alumina ingasetyenziswa njengomthwali, i-catalyst kunye ne-cocatalyst.I-alumina esebenzayo yeGamma inokuba ngumgubo, iigranules, imicu okanye ezinye. Singenza ngokwemfuno yakho. γ-Al2O3, eyayibizwa ngokuba yi-"activated alumina", luhlobo lwezinto eziqinileyo ezisasazekayo ezinemingxuma ephezulu, ngenxa yesakhiwo sayo semingxuma esihlengahlengiswayo, indawo enkulu ethile yomphezulu, ukusebenza kakuhle kwe-adsorption, umphezulu onezibonelelo ze-acidity kunye nokuzinza okuhle kobushushu, umphezulu wemingxuma emincinci oneempawu ezifunekayo zesenzo se-catalytic, ngoko ke iba yi-catalyst esetyenziswa kakhulu, i-catalyst carrier kunye ne-chromatography carrier kwishishini leekhemikhali neoyile, kwaye idlala indima ebalulekileyo kwi-oil hydrocracking, i-hydrogenation refinement, i-hydrogenation reforming, i-dehydrogenation reaction kunye nenkqubo yokucoca i-exhaust yemoto. I-Gamma-Al2O3 isetyenziswa kakhulu njenge-catalyst carrier ngenxa yokulungelelaniswa kwesakhiwo sayo semingxuma kunye ne-acidity yomphezulu. Xa i-γ-Al2O3 isetyenziswa njenge-catalyst carrier, inokuba nefuthe lokusasaza nokuzinzisa izinto ezisebenzayo, ikwabonelela nge-acid alkali active centre, i-synergistic reaction kunye ne-catalytic active components. Ulwakhiwo lwembobo kunye neempawu zomphezulu we-catalyst zixhomekeke kwi-catalyst ye-γ-Al2O3, ngoko ke i-catalyst esebenza kakuhle iya kufunyanwa kwi-catalytic reaction ethile ngokulawula iimpawu ze-gamma alumina carrier.I-alumina esebenzayo yeGamma ngokubanzi yenziwe nge-pseudo-boehmite yayo yangaphambili ngokusebenzisa i-400 ~ 600℃ ukuphelelwa ngamanzi kubushushu obuphezulu, ngoko ke iipropati ze-physicochemical kumphezulu zimiselwa kakhulu yi-pseudo-boehmite yayo yangaphambili, kodwa kukho iindlela ezininzi zokwenza i-pseudo-boehmite, kwaye imithombo eyahlukeneyo ye-pseudo-boehmite ikhokelela kulwahlulo lwe-gamma - Al2O3. Nangona kunjalo, kwezo catalysts ezineemfuno ezikhethekileyo kwi-alumina carrier, kunzima ukuzifezekisa kuphela kulawulo lwe-pseudo-boehmite yangaphambili, kufuneka zithathwe kulungiselelo lwe-prophase kunye nokucubungula emva kokudibanisa iindlela zokulungisa iipropati ze-alumina ukuhlangabezana neemfuno ezahlukeneyo. Xa ubushushu buphezulu kune-1000 ℃ ekusetyenzisweni, i-alumina iyenzeka emva kokuguqulwa kwesigaba: γ→δ→θ→α-Al2O3, phakathi kwazo i-γ、δ、θ zi-cubic close packing, umahluko ulele kuphela ekusasazweni kwee-ion ze-aluminium kwi-tetrahedral kunye ne-octahedral, ngoko olu tshintsho lwesigaba alubangeli utshintsho olukhulu kwizakhiwo. Ii-ion zeoksijini kwisigaba se-alpha zisondelelene kakhulu, amasuntswana e-aluminium oxide adibana kakhulu, indawo ethile yomphezulu yehla kakhulu.
