Abstract
- NaBiZnVO ceramic was investigated as a promising microwave dielectric material for the ultra-low-temperature co-fired ceramic (ULTCC) technology. Dense NaBiZnVO ceramic was prepared using the conventional solid-state method from 560 to 640 °C. X-ray diffraction data show that NaBiZnVO ceramic crystallized into a cubic garnet structure with a space group Ia-3 d. The sample sintered at 600 °C for 4 h has the highest relative density of 96.3 % and exhibits the optimum microwave properties with a relative permittivity of 22.3, a quality factor of 19,960 GHz (at 8.7 GHz), and a temperature coefficient of resonance frequency of +15.5 ppm/°C. The NaBiZnVO ceramic was found to be chemically compatible with highly conductive aluminum and sliver electrode. These results confirm that NaBiZnVO ceramic can be a promising candidate for the ULTCC technology. [ABSTRACT FROM AUTHOR]
