摘要: Abstract Samples of magnetic glass-ceramics were obtained in the system SrO–Fe 2 O 3 –Al –B by heat treatment initial oxide glasses at 600–900 °C. The hexaferrite particles demonstrated hexagonal platelet shape. characterized maximal values coercive forces 6600, 7300, and 7700 Oe depending on chemical composition, which higher than past for SrFe 12 19 based glass-ceramics. Increasing force apparently connected with substitution iron aluminum hexaferrite.
