I-alumina ehlanganisiwe emhlophe iyi-abrasive yezinga eliphezulu, eyenziwe ngempushana yezinga eliphezulu ye-alumina yezimboni ngemva kokuncibilikiswa ezingeni lokushisa eliphezulu elingaphezu kuka-2200 ℃ esithandweni sikagesi esitshekisayo bese siyapholiswa.Isigaba sayo esikhulu sekristalu yi-α-Al2O3, nombala umhlophe.
Njengento ebalulekile yokusetshenziswa embonini ye-abrasive, i-alumina oxide powder emhlophe inezici zayo eziyingqayizivele kanye nokusetshenziswa okucebile
Izici
1. Akuphazamisi umbala wezingxenye ezicutshunguliwe
2. Ngemva kokuqhunyiswa kwesihlabathi, ingaphezulu limhlophe futhi alinakho ukungcola, asikho isidingo sokuhlanza okuyinkimbinkimbi;
3. Inani le-Fe2O3 liphansi kakhulu
4. Isivinini sokucubungula ngokushesha futhi sithuthukise ikhwalithi.
5. Isinyathelo sokukhetha ukususa ukungcola.
