# Ni–Cu–Zn Ferrite Powder Prepared from Steel Pickled Liquor and Electroplating Waste Solutions

## 抄録

In this study, we propose a new method of synthesizing Ni–Cu–Zn ferrite powder using steel pickled liquor and electroplating waste solutions as starting materials. It was found that the Ni–Cu–Zn ferrite powder prepared by a hydrothermal process from the waste solutions shows the formation of cubic ferrite with a saturation magnetization ($M_{\text{s}}$) of 31.5 emu/g and an intrinsic coercive force ($H_{\text{ci}}$) of 19.3 Oe. Upon annealing at 750 °C for 2 h, the saturation magnetization increases to 52.6 emu/g and the intrinsic coercive force reaches 42.8 Oe. This useful method can promote the recycling of industrial waste solution and contribute to the preservation of the earth. Moreover, this method decreases the manufacturing cost in the treatment of the industrial waste solution for electroplating and steel industries.
