Synthesis of Ba(Mg0.8Zn0.2)0.98Y0.021/3Ta2/3O3microwave dielectric ceramics With La2O3-B2O3-ZnO glass for LTCC application
Low-temperature co-fired ceramics(LTCC)technology plays an important role in passive integration and system-on-a-package(SOP).This Technology could co-fire active layers,substrates and electrodes together at a temperature under the fusion points of these prime components.The samples of Ba(Mg0.8Zn0.2)0.98Y0.021/3Ta2/3O3(BMZYT)ceramics with 3 wt%La2O3-B2O3-ZnO(LBZ)glass-fluxed were synthesized bytheconventional solid-state reaction.The effect of LBZ glasses on the sintering behavior,microstructure,phase composition and dielectric properties of BMZYT ceramics have been systematically studied.Different proportions of LBZ glass were added to BMZYT ceramics.With the LBZ additionhasbeen increasing,there is no other phase generation.The sintering temperature of the glass-added BMZYT samples was lowered to 900℃ compared with BMZYT which sintered at 1375℃.LBZ glass served as flux former and conduced to the reactive liquid-phase mechanism.A liquid phase generated by LBZ can greatly promote the densification.The BMZYT ceramicswith 3 wt%LBZ sintered at 900℃ for 6 h shows good microwave dielectric properties: εr=22.29,Q×f=11051 GHz(f=6.923GHz),and τf =5.69 ppm/℃.
