I-SG abrasive yi-polycrystalline alumina abrasive ene-submicron crystalline structure.Inika ukusebenza okuphezulu kokusila kune-alumina abrasives edibeneyo eqhelekileyo, ngenxa yokuba umgca wayo wokusika uqhekeke nge-microscopically kwaye amandla okusika aphezulu agcinwa kumphezulu kunye nokusila kwe-cylindrical.Ivili lokusila elenziwe nge-ceramic abrasive kunye nokuqina okuphezulu kunye nobomi obude, obungamaxesha angama-5-10 kunevili lokusila elenziwe nge-corundum eqhelekileyo. kunamavili e-aluminiyam oxide eqhelekileyo, kunye ne-abrasive yayo yokuzilola yenza imiphetho ebukhali kwizixhobo kwaye ife.
