Glass samples with nominal compositions SrFe 12 O 19 +(12− n )SrB 2 O 4 +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°C, and the resulting glass–ceramics was characterized by XRD, SEM, EDX, and magnetic measurements. SrFe 12 O 19 crystallizes above 700°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°C show coercive force values in the range of 422–455 kA/m.
