摘要

This study investigated the potential applications of microwave dielectric properties of Mg_2SnO_4 ceramics in mobile communication. Mg_2SnO_4 ceramics were prepared using a conventional solid-state method. The X-ray diffraction patterns of the Mg_2SnO_4 ceramics revealed no significant variation of phase with sintering temperature. A maximum density of 4.62 g/cm~3, a dielectric constant (ε_r) of 8.41, a quality factor (Q x f) of 55,100GHz, and a temperature coefficient of resonant frequency (τ_f) of -62ppm/°C were obtained when Mg_2SnO_4 ceramics were sintered at 1550 °C for 4 h.
