I-Fused spinel bubunyulu obuphezulu be-magnesia-alumina spinel grain, eveliswa ngokudibanisa i-magnesia yococeko oluphezulu kunye ne-alumina kwi-exlectric arc furnace. Emva kokuqina kunye nokupholisa, iyatyunyuzwa kwaye ihlelwe ngokwemilinganiselo yeed. Ngenye yezona zinto zixhaphakileyo ezixhathisayo.Ukuba nobushushu obuphantsi be-thermal yokusebenza, zibalaseleyo kwi-high refractoriness ukuzinza kwe-thermal kunye nokuzinza kweekhemikhali, i-magnesia-alumina spinel yinto ecetyiswayo kakhulu ye-refractory ekrwada. Iimpawu zayo ezibalaseleyo ze-tic ezinjengombala omnandi kunye nenkangeleko, ukuxinana okuphezulu kwesambuku, ukuchasana okunamandla ekukhupheni kunye nokuchasana okuzinzileyo kumothuko we-thermal, okuvumela ukuba imveliso isetyenziswe ngokubanzi kwiziko elijikelezayo, uphahla lweziko zombane zentsimbi kunye nokunyibilikiswa kwentsimbi, isamente. i-rotary kiln, i-glass furnace kunye ne-me etallurgical industry etc.
