Abstract
- Li-Zn-Ti ferrite doped with 0.5 wt.% to 16 wt.% HBO-BiO-SiO-ZnO (BBSZ) glass was synthesized using a low-temperature ceramic sintering process. Selected parameters of saturation induction ( B), coercivity ( H), Curie temperature ( T), and complex permeability spectra were measured as functions of doping content, and their relationships with ferrite density and microstructure are discussed. It was found that Li-Zn-Ti ferrite can be fired at low temperature (900°C) with BBSZ glass content varying from 0.5 wt.% to 2 wt.%. The real permeability increased from 80 to 190 in the frequency range from 1 MHz to 3 MHz, the saturation induction B increased from 105 mT to 150 mT at 1 kHz, whereas the coercivity H decreased from 165 A/m to 65 A/m at 1 kHz and the Curie temperature T slightly declined from 155°C to 143°C. These results confirm that this new ferrite material could be used in low-temperature cofired ceramic (LTCC) devices. [ABSTRACT FROM AUTHOR]
