Elucidating the microwave dielectric properties of (Mg(1-x)Znx)2SnO4 ceramics

The microwave dielectric properties of (Mg(1-x)Znx)(2)SnO4 ceramics were examined with a view to their exploitation for mobile communication. The (Mg(1-x)Znx)(2)SnO4 ceramics were prepared by the conventional solid-state method with various sintering temperatures. The X-ray diffraction patterns of the (Mg0.93Zn0.07)(2)SnO4 ceramics revealed no significant variation of phase with sintering temperatures. Dielectric constant (epsilon(r)) of 8.50, quality factor (Q x f) of 186,100 GHz, and temperature coefficient of resonant frequency (tau(f)) of -61 ppm/degrees C were obtained for (Mg0.93Zn0.07)(2)SnO4 ceramics that were sintered at 1550 degrees C for 4 h.
