N2 - The Bi3SbO7 ceramic was prepared by the solid state reaction method and its phase evolution at different temperatures was studied. Low temperature phase α-Bi3SbO7 was formed at about 890 °C and it started to transform to high temperature phase β-Bi 3SbO7 at about 960 °C. Microwave dielectric constants of α-Bi3SbO7 ceramic and β-Bi 3SbO7 ceramic were 43.2 and 37.6, Qf value were 2080 and 5080 GHz, respectively. TCF of α-Bi3SbO7 ceramic was near zero and TCF of β-Bi3SbO7 ceramic was about -120 ppm/°C. The Bi3SbO7 ceramic is a promising candidate for low temperature co-fired ceramic (LTCC) technology due to its large dielectric constant, low dielectric loss at microwave region, low sintering temperature and simple composition.
