Kutentha kwapamwamba calcined aluminium okusayidi ufa ndi calcined mu crystalline mtundu alpha-mtundu aluminiyamu mankhwala pa kutentha yoyenera;calcined ndi calcined α-mtundu alumina monga zopangira, opangidwa ndi mpira mphero Alumina ufa wabwino.Kutentha kwambiri kwa calcined aluminium oxide ufa kumakhala ndi malo osungunuka kwambiri, mphamvu zamakina, kuuma, kukana kwambiri, komanso kusinthasintha kwamafuta.Itha kugwiritsidwa ntchito kwambiri pazida zamagetsi, zoumbaumba zamapangidwe, zida zokanira, zida zosagwira, zida zopukutira, ndi mafakitale ena.
