Glass samples with nominal compositions
SrFe12O19+(12-n)SrB2O4+nSrSiO(3), n=3, 6, 9 were prepared by rapid
quenching of the melt. Processes of glass devitrification were studied.
The samples were annealed at temperatures of 600-900 degrees C, and the
resulting glass-ceramics was characterized by XRD, SEM, EDX, and
magnetic measurements. SrFe12O19 crystallizes above 700 degrees C and
forms nano- and submicron platelet particles with the aspect ratio
depending on the thermal treatment conditions. The glass-ceramic
samples annealed at 900 degrees C show coercive force values in the
range of 422-455 kA/m.
