Study on High Densification M-Type Ferrite Sintering Technology
Year: 2025
Type: article
Abstract: When applied to devices, BaM ferrite materials are required to have magnetic properties such as high saturation magnetization, or microwave properties such as low ferromagnetic resonance linewidth, which require BaM ferrite to be as dense as possible. The density of BaM ferrite can be significantly improved by introducing pre-holding in the sintering process. The density of BaM ferrite can reach 5.06 g/cm3, the sample grain size can reach 100 μm, and the magnetic properties are close to the single crystal state after 1 h of pre-holding. The maximum 4πMs is 4606 Gs and ΔH is 487 Oe when pre-holding for 1 h, indicating its potential for application in microwave devices.
