Corundum yera ikorwa mugihe cy'ubushyuhe buri hejuru ya dogere 2000.Binyuze mubikorwa byinshi birimo guhonyora, gushushanya no gushungura, biruta mubigaragara no gukomera nkibikoresho byakoreshejwe cyane.Corundum yera ntabwo iri hejuru gusa mubukomere, ariko kandi iravunika muburyo, bukomeye mugukata imbaraga.Irakora kandi neza mukwirinda, kwikarishye, kwambara birwanya hamwe nubushyuhe bwumuriro.Hagati aho, irwanya aside na alkali kwangirika n'ubushyuhe bwinshi.Kubwibyo, nkibintu bikomeye cyane, corundum yera ifite ibintu byiza cyane.
