摘要

The prepared [(Mg0.7Zn0.3)]0.95Co0.05]1+δ(Ti1– x Sn x )O3+δ (δ = 0.02) ( x = 0, 0.03, 0.05, 0.07, 0.09, 0.1 and 0.2) ceramics are sintered at 1175–1300°C, the needed sintering temperatures of [(Mg0.7Zn0.3)]0.95Co0.05]1+δ(Ti1– x Sn x )O3+δ (δ = 0.02) ceramics slightly increased with the increase of Sn4+ content. The sintering characteristics of [(Mg0.7Zn0.3)]0.95Co0.05]1+δ(Ti1– x Sn x )O3+δ (δ = 0.02) 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 Sn4+ content and sintering temperatures on the quality values ( Q × f ) and the temperature coefficient of resonant frequency (τf values) of [(Mg0.7Zn0.3)]0.95Co0.05]1+δ(Ti1– x Sn x )O3+δ (δ = 0.02) ceramics at microwave frequency are well developed in this study. As an optimal compose, [(Mg0.7Zn0.3)]0.95Co0.05]1+δ(Ti1– x Sn x )O3+δ (δ = 0.02) successfully demonstrated a dielectric constant of 16.1, a Qxf of 300,000 GHz and a temperature coefficient of resonent frequency value of ?53.8 ppm/°C after firing at a relatively lower sintering temperature of 1250°C.
