Alumina (AL2O3), ni ibintu byoroshye kwambara kandi bikoreshwa mu nganda nyinshi.Iyo bimaze kwirukanwa no gucumura, birashobora gukorwa gusa hakoreshejwe uburyo bwo gusya diyama.Alumina nubwoko bukoreshwa cyane mubutaka kandi buraboneka mubyera bigera kuri 99.9%.Gukomatanya kwubukonje, gukora ubushyuhe bwo hejuru (kugeza kuri 1,700 ° C) hamwe no gukwirakwiza amashanyarazi neza bigira akamaro muburyo butandukanye bwo gusaba.
Hafi ya alumina yuzuye (99,7%) itanga ubushyuhe bwo hejuru bwo kurinda imiyoboro.
