Abstract

The microstructures and the microwave dielectric properties of (1 − x)Mg(Sn0.05Ti0.95)O3–x(Ca0.8Sr0.2)TiO3−y wt% ZnNb2O6 (x = 0.05–0.08, y = 2–8) ceramics system prepared by conventional solid-state route were investigated. The crystalline phases and the microstructures of the ceramics were characterized by means of X-ray diffraction and scanning electron microscopy. Zn2+ partially replaced Mg2+ in Mg(Sn0.05Ti0.95)O3 and formed the ilmenite-type (Mg1−δZnδ)(Sn0.05Ti0.95)O3 phase. Second phase (Mg1−δZnδ)(Sn0.05Ti0.95)2O5 increased remarkably when excess ZnNb2O6 added. ZnNb2O6 as additives could not only effectively lower the sintering temperature of the ceramics to 1320 °C, but also promote the densification. The microwave dielectric properties of specimens were strongly related to ZnNb2O6 and (Ca0.8Sr0.2)TiO3 content. The optimized microwave dielectric properties with ε r  ~ 22.13, Q × f value ~60,613(at 7 GHz) and τ f value ~0.4 ppm/ °C were achieved for (1 − x)Mg(Sn0.05Ti0.95)O3–x(Ca0.8Sr0.2)TiO3–y wt% ZnNb2O6 (x = 0.07, y = 4) sintered at 1320 °C for 2 h.
