Abstract

The microwave dielectric properties of Nd2MoO6 ceramics were investigated with a view to their application in mobile communication. The Nd2MoO6 ceramics were prepared by the conventional solid-state method with various sintering temperatures and sintering times. A maximum density of 6.05 g/cm3 was obtained for Nd2MoO6 ceramic, sintered at 1,350 °C for 4 h. Dielectric constants (ɛ r ) of 10.9–15.4 and quality factor (Q × f) of 7,300–19,200 GHz were obtained at sintering temperatures in the range 1,200–1,400 °C for 4 h. Dielectric constants (ɛ r ) of 14.6–15.4 and quality factor (Q × f) of 11,100–19,200 GHz were obtained for sintering times in the range 2–6 h at a sintering temperature of 1,350 °C. A dielectric constants (ɛ r ) of 15.4, a quality factor (Q × f) of 19,200 GHz, and a temperature coefficient of resonant frequency (τ f ) of −59 ppm/°C were obtained when Nd2MoO6 ceramics were sintered at 1,350 °C for 4 h.
