Preparation, phase stability, sintering behavior, microwave dielectric properties of single-phase Bi2Mo2O9 ceramic and its chemical compatibility with Ag have been investigated. The single-phase Bi2Mo2O9 ceramic can be well densified in the temperature range from 620° to 645°C with relative density about 96%. X-ray diffraction data show that Bi2Mo2O9 has a monoclinic structure (P21/n), with lattice parameters a=11.9664 A, b=10.8089 A, and c=11.8871 A. When sintering temperature ≥650°C, Bi2Mo3O12 appears as a secondary phase. Pure monoclinic Bi2Mo2O9 ceramic sintered at 620°C for 2 h exhibits good microwave dielectric properties with permittivity about 38, Qf value about 12 500 GHz and temperature coefficient of resonant frequency about +31ppm/°C. The permittivity of single-phase Bi2Mo2O9 corrected for porosity is about 40.17. However, the reaction between Bi2Mo2O9 and Ag will affect its further application in low-temperature cofired ceramic.
