Abstract

The system BaO·(Nd_1-xBi_x)₂O ₃·4TiO₂ solid solution containing lithium borosilicate glass were prepared and examined as a low-temperature co-fired ceramics (LTCC). The sintering properties of the low-temperature sintered BaO·(Nd_1-xBi_x)₂O ₃·4TiO₂ with glass frit were investigated using dilatometer, SEM and TEM. The microwave dielectric properties were measured using a network analyzer. The addition of glass to BaO·(Nd _1-xBi_x)₂O₃·4TiO₂ significantly lowered the sintering temperature to ∼900°C in comparison to ∼1300°C for samples without glass. The formation of liquid phase present in the low temperature sintered sample was confirmed using TEM. It was found that thermal properties of the added lithium borosilicate glass dominated the sintering properties of BaO·(Nd_1-xBi_x) ₂O₃·4TiO₂ including shrinkage onset temperature and shrinkage rate. The sample of BaO·(Nd _0.8Bi_0.2)₂O₃·4TiO ₂ with 10wt.% glass sintered at 900°C exhibited a quality factor (Q×f) of 2200GHz, a ε_r of 68, and a τ_f of 55ppm/°C.
