英文摘要: The phase formation and magnetic property evolution processes of the hexaferrite with composition BaO⋅0.9Sc2O3⋅5.1Fe2O3 have been investigated. Results show that when the calcination temperature is lower than 1000 °C, the spinel phase BaFe2O4 and M-type hexaferrite phase BaFe12O19 dominate. The M-type hexaferrite BaFe12−xScxO19 (0 < x ≤ 1.8) appears above 1050 °C and becomes a single phase BaFe10.2Sc1.8O19 above 1200 °C. A two-step decrease of both the coercivity and remanence ratio is observed above 1050 °C, which agrees well with the appearance of soft magnetic phase BaFe12−xScxO19 (0 < x ≤ 1.8). The...
