Abstract
NiCuZn Ferrites, known as preventing EMI/EMC, were prepared and their properties were investigated based on the chemical composition ratio, sintering temperature, and mean particle size. The NiCuZn ferrite made of $Fe_2O_3$ 49.0 mol%, NiO 9.0 mol%, CuO 8.0 mol%, ZnO 34.0 mol% could be applied at the largest range of electromagnetic wave. The optimal calcination and sintering temperature were $900^{\circ}C$ and $1080^{\circ}C$, respectively. The electromagnetic wave loss capacity of its mean particle size $1.12{\mu}m$ was superior to others examined.
