I-alumina edibeneyo emhlophe yenziwe nge-high-purity low-sodium alumina powder ngokunyibilika kwiqondo lobushushu eliphezulu, ukupholisa icrystallization, emva koko ukutyumza.Igrit ye-alumina edityanisiweyo emhlophe iphantsi kolawulo olungqongqo ukugcina ubungakanani bokuhanjiswa kweenkozo kunye nenkangeleko engaguqukiyo.
Imhlophe, i-crystal α ngaphezu kwe-99%, ubunyulu obuphezulu, ubunzima obuphezulu, kunye nokuqina okuphezulu, amandla okusika anamandla, ukuzinza okuqinileyo kweekhemikhali, kunye nokugquma okuqinileyo.
