Umgubo oxutywe we-alumina omhlophe wenziwa ngomgubo we-alumina ophantsi-sodium ngokunyibilika kubushushu obuphezulu, ukupholisa icrystallization, emva koko ukutyumza.Igrit emhlophe edityanisiweyo ye-aluminium oxide yomgubo iphantsi kolawulo olungqongqo ukugcina ukuhanjiswa kobungakanani beenkozo kunye nenkangeleko engaguqukiyo.
Ukwabiwa kobungakanani bengqolowa yomgubo we-alumina odibeneyo omhlophe bumxinwa.Emva kokucwangcisa, ukucoceka okuphezulu komgubo omhlophe we-corundum unengqolowa epheleleyo, imiphetho ebukhali kunye neekona, ukusebenza kakuhle kokusila, ukukhazimla okuphezulu.Ukusebenza kakuhle kokusila kuphezulu kakhulu kune-abrasives ethambileyo efana ne-silica.
Ngenxa yembonakalo entle, umphezulu wento epholisiweyo unokugqiba okuphezulu.Isetyenziswa kakhulu ekusileni nasekupholisweni kweesemiconductors, iikristale, iibhodi zesekethe, i-aluminiyam, intsimbi, intsimbi engatyiwa, ilitye, iglasi, njl.njl. Ngokukodwa kwishishini lokusila kunye nokupholiswa kwentsimbi, i-aluminiyam, ubhedu kunye nezinye izinto zentsimbi kunye noshishino lweglasi. , ibonisa ngokupheleleyo ukusebenza okuphezulu.
Imhlophe, i-crystal α ngaphezu kwe-99%, ubunyulu obuphezulu, ubunzima obuphezulu, kunye nokuqina okuphezulu, amandla okusika anamandla, ukuzinza okuqinileyo kweekhemikhali, kunye nokugquma okuqinileyo.

Akukho mpembelelo malunga nombala weendawo ezicutshungulwayo.
Ingasetyenziselwa kwiinkqubo apho i-residu ye-iron powder inqatshelwe ngokungqongqo.
Ukubunjwa kweenkozo zifaneleke kakhulu kwi-sandblasting emanzi kunye nemisebenzi yokupolisha.
1.Ukuqhunyiswa kwesanti, ukupolisha kunye nokusila isinyithi kunye neglasi.
2. Ukuzaliswa kwepeyinti, i-coating-resistant coating, i-ceramic, kunye ne-glaze.
3.Ukwenziwa kwelitye leoli, ilitye lokugaya, ivili lokugaya, i-sandpaper kunye ne-emery cloth.
4.Ukuveliswa kweembrane zokucoca i-ceramic, iibhubhu ze-ceramic, iiplate ze-ceramic.
5.Ukuveliswa kolwelo lokupholisha, i-wax eqinile kunye ne-wax engamanzi.
6.Ukusetyenziswa komgangatho ongagungqiyo.
I-7.Ukugaya okuphezulu kunye nokupholishwa kweekristale ze-piezoelectric, i-semiconductors, insimbi engenasici, i-aluminium kunye nezinye izinyithi kunye nezingezona.
8.Iinkcazo kunye nokwakheka
