Low Temperature Firing of Li 0.43 Zn 0.27 Ti 0.13 Fe 2.17 O 4 Ferrites with Enhanced Magnetic Properties

In the present work, the Li 0.43 Zn 0.27 Ti 0.13 Fe 2.17 O 4 ferrite, a low temperature sintered gyromagnetic material, was prepared via solid‐state reaction method. A pure spinel phase can be formed with a sintering temperature ranging from 880°C to 920°C, which allows them to be co‐fired with silver. The addition of ZnO–Bi 2 O 3 –SiO 2 ( ZBS ) glass in the Li 0.43 Zn 0.27 Ti 0.13 Fe 2.17 O 4 ferrites contributes significantly to the grain growth and ferromagnetic properties through a low temperature (~900°C) sintering process. Results show that the addition of ZBS glass (0.125–2.00 wt%) cannot only double saturation induction (from ~150 to 300 mT) but also drastically reduce ferromagnetic resonance line width at 9.3 GHz (from 920 to 228 Oe), indicating that ZBS glass is a good candidate for lowing the sintering temperature of LiZnTi ferrites.
