The microwave dielectric properties of low temperature sintered BaO-Nd

O

-TiO

(here after BNT) with a Pb-based glass-ceramics were studied in order to investigate their applicability to Low Temperature Co-fired Ceramics (LTCC) for fabrication of multilayered Radio Frequency (RF) passive components module. The BNT ceramics, with 5∼30 wt% of PbO-TiO

-A1

O

-SiO

based glass-ceramics, were sintered at 105

, which is lower than 130

, sintering temperature of pure BNT ceramics. With increasing the amount of the glass-ceramics, sintering rate of the ceramics become activated due to the softening of glass, resulting in low-temperature densification. BaO-Nd

O

-TiO

microwave ceramics with 20 wt% glass-ceramics exhibit sintered relative densities over 95% and dielectric constant of 72, quality factor of 1500, and temperature coefficient of frequency of +22 ppm/

. This enhanced dielectric properties are attributed to mainly the presence of crystalline phases PbTiO

within the Pb-based glass.
