Abstract
Low-temperature sinterable Ba3TiV4O15 and Ba3ZrV4O15 ceramics have been prepared through conventional solid state ceramic route. Phase purity of the materials has been studied using powder X-ray diffraction technique. The microwave dielectric properties of the materials were studied by Hakki and Coleman post resonator technique and resonant cavity methods respectively using a Vector Network Analyzer. Both Ba3TiV4O15 and Ba3ZrV4O15 ceramics exhibited low dielectric constant and comparatively high unloaded quality factor. At optimum sintering temperature of 800 °C, the temperature coefficient of resonant frequency of Ba3TiV4O15 and Ba3ZrV4O15 ceramics are 10 ppm/°C and −102 ppm/°C respectively. Both compositions exhibited good chemical compatibility with silver and aluminum electrodes.
