Adjustment on resonance frequency stability against the sintering temperature of Sr3V2O8 was realized by adjusting the Sr:V mole ratio. Effects of Sr:V ratio on sintering behavior and dielectric properties of Sr3V2O8 were studied. The sintering temperature was sucessfully reduced to 950 degrees C from 1150 degrees C. With increasing vanadium content, both relative permittivity and quality factor decreased, while the temperature coefficient of resonance frequency shifted from positive to negative values. Especially, a near-zero tau(f) of -1.1 ppm/degrees C along with a low permittivity (epsilon(r)) of 9.8 and a quality factor Q x f of 24 120 GHz was successfully achieved in Sr3-yV2O8-y ceramic (y = 0.6, sintered at 950 degrees C). The wide compositional and processing adjustment window, favorable dielectric performances, and good chemical compatibility with silver render Sr3-yV2O8-y ceramics potential candidates in multilayer electronic devices.
