I-corundum ensundu ekrwada, eyaziwa nangokuthi i-adamantine, iyinto eyenziwe nge-corundum eyenziwe nge-bauxite yekhwalithi ephezulu ehlungiwe njengezinto eziyinhloko zokusetshenziswa, ezihlungiwe esithandweni sikagesi se-arc esishisa kakhulu esingaphezu kuka-2250℃. Inezakhiwo ezinhle kakhulu njengokuqina okuphezulu (ubulukhuni obungu-9, okwesibili kuphela emva kwe-diamod), ukuzinza okuphezulu kokushisa, ukumelana nokuguguleka okuphezulu, ukuqina okuphezulu, kanye nokuzikhiya okuhle kakhulu kanye nokuqhuba ukushisa okuphansi, okwenza ama-abrasives ansundu e-corundum abe nohlu olubanzi lwezicelo emikhakheni eminingi yezimboni.
Ngokuqondile,ama-abrasives ansundu e-corundumingasetshenziswa ukukhiqiza amathuluzi ahlukahlukene okukhuhla, njengamasondo okugaya, amatshe kawoyela, amakhanda okukhuhla, izitini zokusantisa, njll., futhi ingasetshenziswa ukugaya nokupholisha izinsimbi, izinto zobumba, ingilazi nezinye izinto zokuqina okuphezulu. Ngaphezu kwalokho, ama-micropowders e-brown corundum asetshenziswa njenge-metallurgical deoxidiser kanye nezinto ezimelana nokushisa okuphezulu, kuyilapho amakristalu ahlanzekile aphezulu asetshenziswa ekwenziweni kwezinto zangaphakathi zama-semiconductor kanyei-corundum ensunduimicu. Ezinhlelweni zamakhemikhali, i-corundum ensundu isetshenziswa njengemikhumbi yokusabela, amapayipi kanye nezingxenye zephampu yamakhemikhali ngenxa yokumelana kwayo nokuguguleka okuhle kanye nezakhiwo zayo zamandla aphezulu. Iphinde isetshenziswe kabanzi njengento yokucubungula eyenziwe ngobunjiniyela embonini ye-solar photovoltaic, semiconductor, kanye ne-piezoelectric crystal, kanye nasekwakheni izindonga nophahla lwe-multifurnace olushisa kakhulu.
Inqubo yokukhiqizaama-abrasives ansundu e-corundumkufaka phakathi izinyathelo eziningana, okuhlanganisa ukukhethwa kwezinto zokusetshenziswa, ukuchoboza, ukugaya, ukuxuba nokubumba, i-pyrometallurgy, ukupholisa nokuchoboza, ukuhlolwa nokupakishwa, ngasinye sazo okudingeka silawulwe ngokuqinile ukuqinisekisa ikhwalithi nokusebenza komkhiqizo.
