Abstract	Low-temperature sintering and dielectric properties of the Bi(Nb$_{1−x }$Ta$_{ x }$)O$_{4}$ (x = 0.1, 0.3, and 0.5) system was investigated as a function of the zinc borosilicate (ZBS) glass content with a view to applying this system to LTCC technology. The addition of 7 wt% ZBS glass ensured a successful sintering below 900°C. The complete solid solution of Bi(Nb, Ta)O$_{4}$ with an orthorhombic structure was formed and the high temperature form of Bi(Nb, Ta)O$_{4}$ with a triclinic structure was not observed. The second phase of Bi$_{2}$SiO$_{5}$ was observed for all compositions. The non-relative liquid phase sintering (NLPS) occurred and the one-stage sintering was conducted. The Q × f values were improved by the addition of Ta. Bi(Nb$_{0.7}$Ta$_{0.3}$)O$_{4}$ with 7 wt% ZBS glass sintered at 900°C demonstrated 35.8 in the dielectric constant (ɛ $_{r}$), 2,200 GHz in the quality factor (Q × f $_{0}$), and −48 ppm/°C in the temperature coefficient of resonant frequency (τ $_{f}$).
