I-corundum emhlophe yenziwa ngaphansi kwezimo eziphakeme zokushisa ezingaphezu kuka-2000 degrees.Ngezinqubo eziningi ezihlanganisa ukuchotshozwa, ukubunjwa kanye nokusefa, idlula ukubukeka nobulukhuni njengento esetshenziswa kakhulu ekhethekile.I-corundum emhlophe ayigcini nje kuphela ngobulukhuni, kodwa futhi i-brittle ekuthunjweni, inamandla ekunqumeni amandla.Iphinde yenza kahle ekufakeni, ukuzilola, ukumelana nokugqoka kanye ne-thermal conductivity.Phakathi naleso sikhathi, imelana nokugqwala kwe-asidi ne-alkali kanye nezinga lokushisa eliphezulu.Ngakho-ke, njengento eqinile kakhulu, i-corundum emhlophe inezakhiwo ezinhle kakhulu.
