Abstract Ferrite powders BaFe12O19 were studied in the present work after plasma heating and rapid quenching in differentenvironment: in air, in water and on the copper disk. X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), vibration magnetometry (VSM) and Mossbauer spectroscopy (NGR) showed that the powder produced after quenching on the copper disk was in amorphous-crystalline state. The correlation between the annealing temperature and the value of magnetic parameters (coercive field and saturation magnetization) was established. Annealing at 1200 K for 2 hours increases the coercive force up to 6.3 kOe. The processes of crystallization from the amorphous phase, that improve the magnetic properties of barium ferrite, are discussed.
