  The prepared (Mg1-xCox)2(Ti0.95Sn0.05)O4 (x=0.01~0.009) ceramics are sintered at 1275-1425ºC, the needed sintering temperatures of (Mg1-xCox)2(Ti0.95Sn0.05)O4 ceramics slightly increased with the increase of Co4+ content. The sintering characteristics of (Mg1-xCox)2(Ti0.95Sn0.05)O4 ceramics are developed by the X-ray diffraction patterns and SEM observations to find the influence of sintering temperatures and Sn4+ content on the crystal structure and the grain growth. The influence Co4+ content and sintering temperatures on the quality values (Q×f) and the temperature coefficient of resonant frequency (τf values) of (Mg1-xCox)2(Ti0.95Sn0.05)O4 ceramics at microwave frequency are well developed in this study. As an optimal compose, (Mg1-xCox)2(Ti0.95Sn0.05)O4 (x=0.05) successfully demonstrated a dielectric constant of 14.70, a Q×f of 330,000 GHz and a temperature c.. Read More»
