Abstract

Polycrystalline Ba5Nb4O15 (BNO) - BaWO4 (BWO) composite ceramics are prepared by adding their own nanoparticles as a sintering aid. The prepared samples exhibited the maximum relative density of 98.2% at 900°C. The complex dielectric response of these composite ceramics are analysed by Havriliak - Negami (HN) equation. The BNO - BWO composite added with x=3 wt% of their nanoparticles, fired at 900oC displayed the best microwave dielectric properties; er=39 and Q×f0=59.8 THz at 9.44 GHz. The obtained results of BNO - BWO composite makes this material as a potential candidate for LTCC applications.
