I-corundum emhlophe yenziwa phantsi kweemeko eziphezulu zokushisa ngaphezu kwe-2000 degrees.Ngeenkqubo ezininzi ezibandakanya ukutyumza, ukubunjwa kunye nokuhluzwa, iyagqwesa ngenkangeleko kunye nobulukhuni njengesixhobo esisetyenziswa ngokubanzi esikhethekileyo.I-corundum emhlophe ayiphezulu kuphela kwi-hardness, kodwa ibuye i-brittle kwi-texture, inamandla kumandla okusika.Ikwasebenza kakuhle kwi-insulation, ukuzilola, ukumelana nokunxiba kunye ne-thermal conductivity.Okwangoku, iyamelana ne-asidi kunye ne-alkali corrosion kunye nobushushu obuphezulu.Ke ngoko, njengesixhobo esinzima kakhulu, i-corundum emhlophe ineempawu ezintle kakhulu.
