The effect of different alkali metal chloride fluxes on the phase formation and properties of Sr-based hexaferrite, SrFe12O19 materials

摘要: In order to prepare SrFe12O19 materials, the raw SrCO3 and Fe2O3 were annealed with different alkali metal chlorides such as LiCl + NaCl, KCl, CsCl, NaCl KCl CsCl flux at 1200 °C for 5 h. The structural features of materials prepared without have been compared. phase formation properties are sensible fluxes used in synthesis process. fluxes, produced good quality nanocrystalline whereas reaction mixtures yielded mixed materials. NIR reflectance present series varies regardless synthesis. Relatively high is noted even though single A typical hard ferromagnetic hysteresis loop opening observed room temperature (300 K) Plate-like hexagonal grains size microstructural images molten salt method employed work simple efficient production pure using flux, that worth high-tech applications including satellite communications, magneto-optical recording, data storage, electrical microwave devices.
