Abstract

High sintering temperatures applied to Mn-Zn ferrites not only lead to significant energy consumption but also induce discontinuous grain growth in this material. On the other hand, low temperature sintering can reduce energy consumption, and improve the magnetic properties of Mn-Zn ferrites. However, there is limited research on such low temperature sintering. Hence, low-temperature sintered Mn-Zn ferrites were prepared by adding a V₂O₅-Al₂O₃ (VA) sintering aid. The effects of VA sintering aid content and sintering temperature on the crystal structure, microstructure, and magnetic properties of Mn-Zn ferrites were investigated. The VA sintering aid maintained the spinel crystal structure, reduce the sintering temperature and promote grain growth. As the VA content increased, the values of B_S and power loss (P_CV) first increased and then decreased. For a VA mass fraction of 0.20 wt%, the Mn-Zn ferrites sintered at 1250 °C, and had excellent performance, with μ_i = 1168 at 10 kHz and P_CV@100 kHz/200 mT = 263.20 kW/m³ at room temperature.
