Abstract
JFE Steel Group developed a new fine iron oxide powder “JC-FH04.” Fine magnetic powders, which are obtained by applying a wet synthesis method, are oxidized by heating to produce high purity fine iron oxides with specific surface areas above 1.2 × 104 m²/kg. It is confirmed that the sintering temperature of NiCuZn ferrites made from the developed fine iron oxide is lower than that made from a conventional spray roasted iron oxide.
