Fused spinel yakakwira kuchena magnesia-alumina spinel tsanga, iyo inogadzirwa nekusanganisa yakakwira kuchena magnesia uye alumina muchoto cheexlectric arc. Mushure mekusimba uye kutonhora, inopwanyika uye yakagadzikwa kuti ide ed saizi. Ndiyo imwe yeanonyanya kupikisa refractory compounds.Kuva nekushisa kwekushisa kwekushanda kwakadzika, kwakatanhamara mukukwirira kwekushisa kwekushisa uye kugadzikana kwemakemikari, magnesia-alumina spinel inokurudzirwa zvikuru refractory raw material. Yayo yakanakisa hunhu tic senge yakanakisa ruvara uye chitarisiko, yakakwira yakawanda density, kuramba kwakasimba kuexfoliation uye kugadzikana kuramba kuvhunduka kwemafuta, izvo zvinoita kuti chigadzirwa chishandiswe zvakanyanya mumoto unotenderera, denga revira remagetsi simbi uye kunyungudutswa kwesimbi, simende. rotary kiln, girazi choto uye ini etallurgical maindasitiri nezvimwe.
