Mo Behavior in Mn-Zn Ferrite at High Temperatures Part 2: Sinter Mechanism of Mo in Fe-Rich Mn-Zn Ferrites

Abstract:

Mo behavior in Fe-rich Mn-Zn ferrites during sintering process was studied by adding MoO₃ or MnMoO₄ as additive. The influences of the additive amounts and treatment temperatures on microstructure, density, porosity as well as magnetic properties were investigated. It is found that formation of MnMoO₄ in the grain boundary plays an important role. Saturation flux density (Bs) at 373 K as high as about 513mT could be obtained when the equivalent Mo content is 133ppm. Based on the experimental results, a new hypothesis is proposed to explain why proper Mo addition is essential to obtain ferrites of good qualities.
