Low temperature sintering and ferromagnetic properties of Li0.43Zn0.27Ti0.13Fe2.17O4 ferrites doped with BaO-ZnO-B2O3-SiO2 glass

摘要

In this study, effects of a BaO-ZnO-B2O3-SiO2 (BZBS) glass on the ferromagnetic properties of Li0.43Zn0.27Ti0.13Fe2.17O4 ferrites were systematically investigated. Through the solid-state reaction process, it was observed that a pure spinel phase was obtained with the sintering temperature raging from 880 degrees C to 920 degrees C, indicating the compatibility of co-firing with silver. Results revealed that the addition of BZBS glass significantly promoted grain growth and enhanced ferromagnetic properties of the Li0.43Zn0.27Ti0.13Fe2.17O4 ferrites. With an optimized addition of BZBS glass (2.0 wt.%), the saturation induction was increased from similar to 100 to 285 mT and the FMR line width at 9.3 GHz was dramatically reduced from similar to 800 to 275 Oe. This study indicates that BZBS glass is a promising candidate for low temperature cofired ceramics (LTCC). (C) 2015 Elsevier B.V. All rights reserved.
