I-SG abrasive iyi-polycrystalline alumina abrasive ene-submicron crystalline structure.Inikeza ukusebenza okuphezulu kokugaya kunama-abrasives e-alumina ahlanganisiwe avamile, ngenxa yokuthi unqenqema lwawo luqhekeka nge-microscope futhi amandla okusika aphakeme agcinwa endaweni engaphezulu kanye ne-cylindrical grinding.Isondo lokugaya elenziwe nge-ceramic abrasive elinokuqina okuphezulu nokuphila isikhathi eside, okuyizikhathi ezingu-5-10 kunesondo lokugaya elenziwe nge-corundum evamile. kunamasondo e-aluminiyamu oxide avamile, futhi i-abrasive ezilolayo ikhulisa imiphetho ebukhali kumathuluzi futhi iyafa.
