Abstract
The microwave dielectric properties of Li2SnO3 ceramics were investigated with a view to the use of such ceramics in mobile communication. Li2SnO3 ceramics were prepared using the conventional solid-state method with various sintering temperatures. Dielectric constants (ε
r
) of 11.3–12.0 and unloaded quality factor (Q
u
× f) of 4,900–13,100 GHz were obtained at sintering temperatures in the range 1,300–1,375 °C for 2 h. A maximum apparent density of 4.99 g/cm3 was obtained for Li2SnO3 ceramic, sintered at 1,325 °C for 2 h. A dielectric constant (ε
r
) of 11.4, an unloaded quality factor (Q
u
× f) of 13,100 GHz, and a temperature coefficient of resonant frequency (τ
f
) of 14 ppm/°C were obtained when Li2SnO3 ceramics were sintered at 1,325 °C for 2 h.
