According to recent research published in the Journal of the American Ceramic Society, "Preparation, phase composition, microwave dielectric properties, and chemical compatibility with silver and aluminum electrodes were investigated on a series of single-phase compounds in the Bi2O3-MoO3 binary system. All materials have ultralow sintering temperatures
"The beta-Bi2Mo2O9 single phase has a positive temperature coefficient of resonant frequency (TCF) about +31 ppm/degrees C, with a permittivity epsilon(r) = 38 and Q(f) = 12 500 GHz at 300 K and at a frequency of 6.3 GHz. The alpha-Bi2Mo3O12 and gamma-Bi2MoO6 compounds both have negative temperature coefficient values of ...
