چکیده انگلیسی
The FeSiBPNbCu amorphous magnetic powder with partial crystallization is successfully synthesized using low purity industrial raw materials by gas atomization. The magnetic powder cores (MPCs) are then produced from the mixture of the FeSiBPNbCu powders with 2â¯wt % epoxy resin as insulation and bonding materials by cold pressing under a compact pressure of 1800â¯MPa. Evolution of the high-frequency properties for the MPCs with respect to the annealing temperature is systematically studied. The results show that upon annealing at the optimum temperature, the cores exhibit excellent magnetic properties, including high initial permeability of 86 with a high frequency stability up to 10â¯MHz, high quality factor of 110â¯at 1â¯MHz, and low core loss of 1290â¯mW/cm3 at 100â¯kHz for Bmâ¯=â¯0.1â¯T. It is emphasized that the MPCs prepared by partially crystallized magnetic powders can also achieve lower core losses and higher magnetic permeability, which is of great significance in industrial production.
