- Аннотация: Glasses with the nominal compositions SrFe12O19 + nNa(2)Sr(2)B(4)O(9) (n = 4, 6, 8, 10) and SrFe12O19 + 6Na(2)Sr(3)B(4)O(10) were prepared via rapid quenching of oxide melts and were then heat-treated between 500 and 800 degrees C in order to produce glass-ceramics containing fine SrFe12O19 particles. The materials were characterized by x-ray diffraction, differential thermal analysis, electron microscopy, and magnetic measurements. The crystallization behavior of the glasses was investigated. The coercivity of the glass-ceramics was shown to increase with heat-treatment temperature, up to 486 kA/m. By dissolving the nonmagnetic matrix of the glass-ceramics with the nominal compositions SrFe12O19 + 6Na(2)Sr(3)B(4)O(10) and SrFe12O19 + 4Na(2)Sr(2)B(4)O(9), submicron-sized strontium hexaferrite particles were obtained.
