Ubushyuhe bwo hejuru bubara ifu ya aluminium oxyde ibarwa muburyo bwa kristaline yo mu bwoko bwa alufa yo mu bwoko bwa alumina ku bushyuhe bukwiye;kubarwa no kubara α-ubwoko bwa alumina nkibikoresho fatizo, bikozwe no gusya umupira Alumina ifu nziza.Ubushyuhe bwo hejuru bubara ifu ya aluminium oxyde ifite aho ishonga cyane, imbaraga zumukanishi, ubukana, kwihanganira cyane, hamwe nubushyuhe bwumuriro.Irashobora gukoreshwa cyane mubikoresho bya elegitoroniki, ububumbyi bwububiko, ibikoresho byangiritse, ibikoresho birwanya kwambara, ibikoresho byo gusya, nizindi nganda.
