<P>PROBLEM TO BE SOLVED: To provide an iron oxide particle which is well balanced in high flowability, low aggregation, high electric resistance and magnetic characteristics and has high acid resistance and its production method. <P>SOLUTION: This iron oxide particle consists of multiple iron oxide of Ti and Fe existing on the particle surface. Also, the existing amount of the Ti component in the multiple iron oxide of the iron oxide particle is 0.05 to 5wt% in terms of Ti based on the entire part of the iron oxide particle. Also, the iron oxide particle is Ti:Fe=1 to 100:1 in the molar ratio of the Ti and Fe forming the multiple iron oxide. <P>COPYRIGHT: (C)2004,JPO |
