Aluminium oxide ke ntho ea inorganic e nang le foromo ea lik'hemik'hale A1203, motsoako o thata haholo o nang le ntlha ea ho qhibiliha ea 2054 ° C le ntlha e belang ea 2980 ° C.Ke kristale ea ionic e ka bang tengionizedka mocheso o phahameng 'me e atisa ho sebelisoa ha ho etsoa thepa ea refractory.Calcined alumina le aluminium ka bobeli li na le ntho e tšoanang, empa ka lebaka la mekhoa e meng ea tlhahiso le liphapang tse ling tsa ts'ebetso, e le hore tse peli tse sebelisoang ts'ebetsong 'me kahoo ho tla ba le phapang e itseng.
Alumina ke minerale e ka sehloohong ea aluminium ka tlhaho, e tla siloa ebe e kenngoa ka tharollo ea sodium hydroxide ea mocheso o phahameng ho fumana tharollo ea alumina ea sodium;filthara ho tlosa masala, pholisa filtrate le ho eketsa likristale tsa aluminium hydroxide, kamora nako e telele e hlohlelletsang, tharollo ea alumina ea sodium e tla bola le ho theola aluminium hydroxide;arola precipitate ka ntle 'me ue hlatsoe, ebe calcine e 950-1200 ° C ho fumana c-mofuta alumina phofo, calcined Alumina ke c-mofuta alumina.Libaka tse qhibilihang le tse belang li phahame haholo.
Calcined alumina ha e qhibilihe ka metsing le acid, e tsejoang hape e le aluminium oxide indastering, 'me ke thepa ea motheo e tala bakeng sa tlhahiso ea tšepe ea aluminium;e ka boela ea sebelisoa ha ho etsoa litene tse sa tšoaneng tsa refractory, li-crucibles refractory, li-tubes tsa refractory le lisebelisoa tsa laboratori tse hanyetsanang le mocheso o phahameng;e ka boela ea sebelisoa e le abrasive, retardant flame and filler;bohloeki bo phahameng ba calcined alumina hape ke thepa e tala bakeng sa tlhahiso ea corundum ea maiketsetso, lejoe le lefubelu la maiketsetso le lejoe le leputsoa;e boetse e sebelisoa bakeng sa tlhahiso ea li-substrates tsa boto bakeng sa lipotoloho tsa sejoale-joale tse kholo tse kopaneng.Calcined alumina le aluminium ts'ebetsong ea tlhahiso le likarolo tse ling li fapane hanyane, libaka tsa indasteri tse sebetsang le tsona li fapane, kahoo ha ho rekoa lihlahisoa pele ho ea pele ho fumana libaka tse khethehileng tsa tšebeliso.
