摘要：

Nanocrystalline SrFe12O19 has been prepared by microwave hydrothermal method at 473 K/90 min, subsequently annealed at different temperatures using microwaves (2.45GHz). The average particle size of the powders was found to be 48 nm. The plate shape grains were observed in FE-SEM at 1073 K. The crystals exhibited the typical hexagonal ferrite growth habit with a plate-like geometry. The effects of microwave sintering temperature on crystallinity, morphology and magnetic properties have been investigated. The grain sizes of sintered hexaferrites are in the range of 250 to 890 nm. The value of M-s=58 kAlm and H-c=125 kA/m was obtained at 1173 K/1h.
