Abstract

A temperature stable low-firing microwave dielectric ceramic Ba2LaV3O11 was prepared by the conventional solid state reaction method. Excellent microwave dielectric properties were obtained in Ba2LaV3O11 ceramic sintered at 840 °C, with a permittivity of 12.8, a quality factor of 31,800 GHz (at 9.9 GHz), and a temperature coefficient of resonance frequency of −14 ppm/°C. Ba2LaV3O11 ceramic was found to be chemically compatible with silver at 840 °C based on XRD and EDS analysis of the co-fired sample with 20 wt% silver powders. All the results indicate that the Ba2LaV3O11 ceramic might be a promising candidate for low temperature cofired ceramic technology. Further, the effects of ionic polarizability, packing fraction and bond valence on the microwave dielectric properties of Ba2MV3O11 (M = La and Bi) ceramics were discussed.
