Abstract

The phase composition, microstructures, sintering behavior, and microwave dielectric properties of Ba0.33Sr0.67TiO3–Ba4Sm9.33Ti18O54 ceramics prepared via conventional solid-state route were systematically investigated as a function of the Ba0.33Sr0.67TiO3 molar fraction and sintering temperature. All the sintered ceramics only exhibited a single orthorhombic tungsten bronze structure BaSm2Ti4O12 phase. And all samples sintered at 1400 °C showed fully dense and homogeneous microstructures. The variation of bulk density and dielectric properties are related with the Ba(Zn1/3Nb2/3)O3 molar fraction, but not with a same trend. As Ba ions in A1 sites are substituted by Sr ions, Q × f values enhanced dramatically. The optimum microwave dielectric properties with an εr value of 80.13, a Q × f value of 11386 GHz (at 3.5 GHz), and a τf value of − 0.34 ppm/°C were obtained for 0.03Ba0.33Sr0.67TiO3–0.97Ba4Sm9.33Ti18O54 ceramics sintered at 1400 °C for 4 h.
