Microwave dielectric ceramics of Ba2Ti9O20 were prepared by adding PbO-B2O3-SiO2 (PBS) as a liquid phase sintering aid. With the addition of 5 wt% PBS, dense and single-phase Ba2Ti9O20 dielectric resonators could be fabricated at a sintering temperature below 1200°C. The microwave dielectric properties of PBS-Ba2Ti9O20 ceramics were found to depend upon the density, the amount of liquid phase and the sintering temperature. Although glass addition results in a decrease of the dielectric properties, the sintered PBS-Ba2Ti9O20 ceramics still exhibit much better dielectric properties than that of pure Ba2Ti9O20 ceramics at low sintering temperatures.
