Arc melting yielded the alloys, which were then prepared into amorphous ribbons using the rapid cooling process of melt spinning, followed by crushing into powder. The uncoated and SiO2 coated powders were sintered into toroidal shapes, and their properties were compared before and after the coating process. The x = 0 composition suppressed crystallization during the sintering process due to its high glass-forming ability, yielding a higher density than the x = 2.3 composition owing to high plastic deformation. Although SiO₂ coating increased hysteresis loss, eddy current loss decreased at high frequencies, reducing core loss. x = 0 composition exhibited higher corrosion resistance whereas x = 2.3 composition exhibited better magnetic properties, such as saturation magnetization and permeability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語)：\u003c\/strong\u003eIn this study, Fe71.2+x(C, Si, B, P)24.5(Cr, Al)4.3–x (x = 0, 2.3) amorphous alloys were used to fabricate amorphous powder cores, and their magnetic, mechanical, and corrosion properties were evaluated.
